Activated carbon iodine adsorption effect is a water treatment method that uses the functions of activated carbon such as physical adsorption, chemical adsorption, oxidation, catalytic oxidation and restoration to remove pollutants in water. Three ways to easily identify the level of activated carbon adsorption value.

Iodine value of activated carbon: Iodine value is an important performance parameter of activated carbon. The iodine value of fruit shell, bamboo charcoal, and coal is in the hundreds, and the iodine value of activated carbon raw materials ranges from 800, 850, 900, 950, 1000, 1100 mg/g, etc. , the adsorption ability is also different. Activated carbon coconut shell with the same iodine value has the best adsorption effect on small fractions, and different activated carbons are used to select different raw materials.

Decolorization effect: Another manifestation of the adsorption capacity of activated carbon is the decolorization ability. Activated carbon has the unique ability to turn colored liquid into light-colored or colorless, which is actually caused by the adsorption of pigment molecules in colored liquid by activated carbon. Because of this characteristic of activated carbon, it is widely used in the production process of brown sugar to white sugar in the field of sugar industry.

Bubble rate: put a small amount of activated carbon into the water, because of the penetration effect of water, the water will gradually soak into the pore structure of the activated carbon, forcing the air in the pores to be discharged, and then a series of extremely fine bubbles will be generated, and a fine line will be pulled out in the water. Bubble lines, the more intense this phenomenon occurs and the longer it lasts, the better the adsorption of activated carbon.
