Why Need to Choose Water Washed Activated Carbon?

The main purpose of water-washed activated carbon products is to remove surface impurities, improve pore structure and improve adsorption performance. ‌ Activated carbon will carry some impurities and soluble substances during the production process, which may affect its adsorption performance. Through water washing treatment, these impurities can be effectively removed, thereby improving the purity and adsorption performance of activated carbon‌. In addition, water washing can also reduce the ash content of activated carbon, improve its pore structure, make it more uniform and orderly, thereby improving its adsorption efficiency and life‌. The specific steps and precautions for water-washed activated carbon include: first, avoid using fresh tap water, because the chlorine in tap water will reduce the adsorption life of activated carbon; second, the impurities can be helped to fall off by stirring or shaking during the water washing process; finally, it should be thoroughly rinsed after water washing to prevent impurities from remaining‌. Through water washing treatment, the adsorption performance and service life of activated carbon can be significantly improved, making it more suitable for various complex environmental conditions. For example, in water treatment systems, water-washed activated carbon can better remove harmful substances such as organic matter, microorganisms and residual...

The Difference Between Biochar and Activated Carbon

Although biochar and activated carbon are both composed of carbon elements and have adsorption capabilities, they have significant differences in structure and application fields. And today we will mainly talk about it. Difference Between Biochar and Activated Carbon 1. Composition and structure: Biochar is mainly composed of carbon elements, with loose and porous characteristics. Its pores are unevenly distributed, with both macropores and micropores and mesopores, and the specific surface area is usually within 400 square meters per gram. Activated carbon is also composed of carbon elements, but it is looser than ordinary charcoal and has stronger adsorption capacity. Activated carbon is mainly microporous, with a specific surface area of more than 1000 square meters per gram. Even activated carbon prepared using seaweed as raw material can have a specific surface area of about 2000. 2. Application areas: Biochar is widely used in agriculture, industry, environment, new energy and other fields. For example, in the agricultural field, biochar can improve the water holding capacity and nutrient supply of the soil, increase microbial activity, and help increase crop yields. In the environmental field, biochar, as an excellent adsorption material, can remove pollutants in the environment. Activated carbon has excellent adsorption properties...

Factors That Affect The Adsorption Of Activated Carbon On Dioxins

The pore structure of activated carbon mainly includes specific surface area, pore volume and pore size distribution, which are key parameters affecting the adsorption performance of activated carbon and important factors affecting dioxin adsorption. The adsorption of dioxin on activated carbon is essentially a pore filling process. After the dioxin molecules contact the surface of activated carbon through external diffusion, they diffuse into the pores through the pore channels on the surface of activated carbon. Today we will explain its influence in detail. Factors affecting the adsorption of dioxin by activated carbon Pore size distribution: The pore size of activated carbon needs to match the size of dioxin molecules for effective adsorption. The suitable pore size range is 2.0~5.0nm. Specific surface area: The larger the specific surface area, the stronger the adsorption capacity. Generally, the specific surface area is required to be greater than 500m²/g. Pore volume: Pore volume and pore volume are also important factors affecting the adsorption effect, and the specific pore volume is usually required to be greater than 0.2cm³/g. Effects in practical applications In practical applications, activated carbon achieves effective adsorption and elimination of dioxins through its unique pore structure and physical and chemical properties. For...

Principle of Mercury Removal by Activated Carbon

Activated carbon is a kind of micro-quality carbon material made of carbon-containing materials. It is black in appearance, odorless, non-toxic, has a developed internal pore structure, a large specific surface area, and strong adsorption capacity. It is a commonly used adsorbent. It makes mercury vapor react with sulfur more easily and more effectively to produce mercury sulfide, which is deposited in the pores of activated carbon to achieve the purpose of removing mercury. It is suitable for removing mercury vapor in airflow in places where conventional methods are difficult to remove mercury. Ensure production safety and environmental protection standards. Principle of activated carbon adsorption of mercury: Activated carbon is a highly adsorbent with a large number of pores and surface area and good adsorption performance. For harmful metal elements such as mercury, they are mainly adsorbed by activated carbon through physical adsorption and chemical adsorption. Physical adsorption refers to the monolayer of mercury atoms formed on the pores and surfaces of activated carbon. This adsorption is reversible and weakens with increasing temperature. Chemical adsorption refers to the adsorption of mercury ions by the active functional groups of activated carbon and the combination with the active functional groups through chemical bonds....

Relationship Between Methylene Blue And Iodine Adsorption Values Of Activated Carbon

Methylene blue adsorption value and iodine adsorption value are two different indicators to measure the performance of activated carbon, each reflecting different characteristics of activated carbon. ‌ The methylene blue adsorption value is mainly used to characterize the decolorization ability of activated carbon. The molecular diameter of methylene blue is larger than that of iodine molecules, so the methylene blue value is usually used to represent the number of mesopores in activated carbon, which is crucial for the decolorization process. The higher the methylene blue value, the stronger the decolorization ability of activated carbon is usually, which means that the decolorization effect is better at the same unit weight. ‌Iodine adsorption value is mainly used to characterize the adsorption ability of activated carbon for small molecules, especially for micropores with a diameter of less than 1.0nm. The diameter of iodine molecules is only 0.335nm, so the iodine value reflects the degree of development of activated carbon micropores, which is very important for the adsorption of small molecular impurities. The higher the iodine value, the stronger the adsorption capacity of activated carbon, and the more effectively it can remove impurities such as organic matter, residual chlorine, heavy metal ions in water,...
