What is the chemical adsorption of columnar activated carbon0dingxinda92021-01-10 23:26:18
In physics, activated carbon is fused with raw materials based on intermolecular force or London dispersion force. Activated carbon cannot be effectively combined with certain compounds, including alcohols, alcohols, ammonia, strong acids and alkalis, metals and most inorganic compounds such as lithium, sodium, iron, lead, arsenic, fluorine and boric acid. Activated carbon can absorb iodine well. In fact, the iodine value mg/g (ASTM D28 standard method test) is used as an indicator of total surface area. silver loaded activated carbon  Activated carbon can be used as a substrate of various chemicals to improve its adsorption capacity for some inorganic (and organic) compounds, such as hydrogen sulfide (H2S), ammonia (NH3), formaldehyde (hcoh), mercury (Hg) and radioisotope iodine -131 (131I). This property is called chemical adsorption. Chemical activation of activated carbon: first impregnate with phosphoric acid or potassium hydroxide, sodium hydroxide or zinc chloride, and then carbonize in the range of 450-900°C. It is believed that the carbonization activation process and the chemical activation process proceed simultaneously. In some cases, this technique may be problematic, for example, trace amounts of zinc may remain in the product. However, chemical activation of activated carbon is better than physical activation because the temperature required to activate the material is lower and the time required is shorter.   Activated carbon can be used as a substrate of various chemicals to improve its adsorption capacity for some inorganic (and organic) compounds, such as hydrogen sulfide (H2S), ammonia (NH3), formaldehyde (hcoh), mercury (Hg) and radioisotope iodine -131 (131I). This property is called chemical adsorption.

What benefits of activated carbon attract your attention 0dingxinda92020-11-08 22:23:20
Dog deodorizer Canines are notorious for their smelly gas. In a study published in a 2001 edition of the Journal of American Veterinary Medical Association, researchers discovered that activated charcoal reduced the hydrogen sulfide levels in canine subjects’ gas by 71 percent. Hydrogen sulfide is the compound that makes our furry friends’ flatulence so unbearable; it might be worth hiding some activated charcoal in a spoonful of peanut butter for your dog’s next treat. Emergency poisoning or overdose treatment Activated charcoal is often used in emergency rooms due to its ability to help eliminate toxins from the stomach. When a patient comes in having ingested a severely toxic substance, if taken quickly enough, activated charcoal can help by absorbing the toxins that remain in the person’s stomach. activated carbon supplier  This is also useful for overdose patients or patients experiencing alcohol poisoning, as the charcoal will absorb the drug or alcohol before it is too late. Face masks Many skincare products, such as face masks and cleansers, contain activated charcoal in the belief that it absorbs dirt and other contaminants from your skin. Dr. Sejal Shah, a dermatological surgeon, agrees. “[The charcoal] basically acts like a magnet for dirt, oil, and other impurities,” he explains. “But it depends on physical contact, so it needs to sit on the skin to be effective.” Face masks are usually left on the skin for some time, so the use of activated charcoal makes a lot of sense. Insect bite relief Activated charcoal can be useful for skin irritation, especially in the summer. When a mosquito bites, it injects its saliva into your skin to keep your blood flowing, and the chemical agents involved cause that itchy awful feeling and inflammation. Activated charcoal can work to absorb these allergenic proteins, therefore relieving the  Regulation of cholesterol During one study, activated charcoal successfully reduced LDL (bad cholesterol) and increased HDL (good cholesterol) when participants took small doses throughout the day. If you do take activated charcoal, just be sure to take it separately from any other medications — it will absorb those, too.

Adsorption capacity refers to the amount of adsorbents adsorbed on the adsorbent per unit mass under certain conditions. It is usually expressed in terms of K adsorbents /kg of adsorbent or mass percentage, which is a sign of the adsorption capacity of the adsorbent. In industry, the amount of adsorption is called the activity of the adsorbent.activated carbon powder suppliers  The activity of the adsorbent can be expressed in two ways :(1) the static activity of the adsorbentUnder certain conditions, the equilibrium adsorption capacity of the adsorbent is its static activity.For a certain adsorption system, the static activity depends only on the adsorption temperature and the concentration or partial pressure of the adsorbed substance.   Dynamic activity of adsorbents Under certain operating conditions, the gas mixture by adsorption bed, adsorption by adsorption, adsorption after a period of time, when starting from the adsorbent in the laminar flow of the gas adsorbed mass (or its concentration reaches a specified value), think bed fire, adsorption properties of adsorbent adsorption quantity at this time is called dynamic activity of adsorbent. The activity is not only related to the characteristics of adsorbents and adsorbents, but also related to temperature, concentration and operating conditions. 
Why activated carbon granular shell activated carbon has such a good effect02021-06-28 18:55:05
High-quality granular activated carbon must have good adsorption performance and strength. Like powdery activated carbon, the adsorption performance of granular activated carbon depends largely on the characteristics of pore structure. The adsorption performance index can be analyzed and characterized by different methods, such as the decolorization performance of activated carbon expressed by methylene blue. Other performance indexes include iodine adsorption value, caramel decolorization rate, etc.dxdcarbon carbon  The pore structure characteristics and specific surface area of activated carbon are usually obtained by measuring nitrogen adsorption isotherm at low temperature with adsorption In addition, the adsorption capacity of activated carbon also has a great relationship with its internal pore structure, pore size distribution and surface chemical properties. activated carbon suppliers in uae  Chemical method in addition to certain micropores, macropores, there are more mesopores (transition pores), so it is more suitable for the application of liquid phase, adsorption of larger molecules of substances, such as sugar solution has a good decolorization effect; When purifying water quality, it can also remove the colored material well and achieve the specified chroma requirements. The kinetic activity value of adsorbent is the main basis for the design of adsorption system. The adsorption rateThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, the adsorption process can be divided intoThe adsorption process often takes a long time to reach equilibrium, and the contact time is limited in the actual production process.Therefore, the amount of adsorption depends on the adsorption rate, and the adsorption rate is related to the adsorption process, which can be divided into the following steps (1) External diffusion, the adsorbate from the main air flow through the air film around the particles to the outer surface of the adsorbent; (2) Internal diffusion, the adsorbate from the outer surface through micropores to the surface of the adsorbent micropores (3) adsorption, the adsorbent reached the microporous surface of the adsorbent is adsorbed (4) The desorbed adsorbate diffuses to the main body of the gas phase through internal and external diffusionPhysical adsorption process is generally controlled by internal and external diffusion, chemical adsorption is controlled by both surface dynamics and internal and external diffusion.Because of the complexity of the adsorption process and many influencing factors, it is difficult to derive the rate theoretically, so it is generally determined by experience or model experiment.
