Abstract

The invention discloses a heavy metal adsorbing material prepared from a walnut shell. The heavy metal adsorbing material is prepared from, by weight, 21-25 parts of walnut shell, 12-16 parts of kaolin, 4-7 parts of lignosulfonate, 2-5 parts of aluminum chlorohydrate, 3-6 parts of glutathione and 2-5 parts of guggulsterone. The invention further discloses the preparation method of the heavy metal adsorbing material prepared by the walnut shell. The prepared heavy metal adsorbing material has good adsorption effect on heavy metal lead ions and heavy metal cadmium ions, the adsorption performance is excellent, and the heavy metal adsorbing material and the preparation method can be applied to the field of heavy metal treatment.

Description

technical field [0001] The invention relates to the technical field of heavy metal adsorption materials, in particular to a heavy metal adsorption material prepared from walnut shells and a preparation method thereof. Background technique [0002] Heavy metals are toxic elements that can accumulate in organisms. With the development of industry, heavy metal pollution has been widely valued. After entering the environment, heavy metals will accumulate and enrich in the biological chain, and cannot be biodegraded. They can be latent in the environment for a long time. It enters the human body along with the food chain and seriously endangers life and health. At present, the methods for removing heavy metal ions in water generally include: coagulation method, chemical precipitation method, membrane separation method, ion exchange resin method, biological method, adsorption method, etc. The coagulation method is to use the floc formed by adding a coagulant to absorb and remove ...
