Embodiment

[0020] Configure activated carbon for medicinal decolorization:

[0021] S1 selected raw materials, choose activated carbon as the base carbon, the molasses value of activated carbon is ≥ 210, the moisture content is ≤ 5%, the strength is ≥ 85%, and the iodine adsorption value is ≥ 900;

[0022] S2 Prepare the first mixed solution, mix pure water with a mass ratio of 4:1 and ammonium bicarbonate, heat to 40-60°C while stirring, keep warm for 10-15min, and finally heat to 60°C;

[0023] S3 once impregnated, put 20g of the first mixed solution in every 500ml of pure water, the pure water and the first mixed solution form the mixed additive solution, the mass of the mixed additive solution accounts for the percentage of the mass sum of the activated carbon = the water capacity of the activated carbon - the activated carbon Moisture content, the activated carbon in step S1 is placed in the mixed additive solution, stirred rapidly, and then the activated carbon absorbed with the fi...

Abstract

The application discloses a preparation process of active carbon for medicinal decolorization, comprising the following steps: selecting raw materials, preparing a first mixed solution, once impregnating, once calcining, preparing a second mixed solution, second impregnating, and second calcining. The invention has the advantages of high decolorization efficiency, no film blocking phenomenon, high strength, strong adsorption capacity, large adsorption capacity, less ash content, fast adsorption rate and the like.

Description

technical field [0001] The application relates to activated carbon, in particular to a preparation process of activated carbon for medicinal decolorization. Background technique [0002] Activated carbon is a porous substance with very good filtration performance. It has been applied in many fields, especially in the field of environmental protection. Whether it is purifying water or air, it has become the current protagonist, and it also plays an irreplaceable role in the field of medicine. role. [0003] Most of the products in the existing technical solutions will have film blocking after decolorization, which will cause difficulties for users in use and slow down the decolorization efficiency. However, this patent provides a preparation process of activated carbon for medicinal decolorization, in which A substance that can prevent membrane clogging, speed up filtration, and improve production efficiency, so that the product will not be clogged during use.
