Abstract

The invention discloses an adsorbent capable absorbing a soil heavy metal. The adsorbent is characterized by being prepared by the following raw materials, by weight part: 8-15 of calcium carbonate fiber, 20-40 of tetrabutyl titanate, 3-5 of silica sol, 6-8 of calcium aluminate, 60-80 of volcanic rock, 6-9 of PA6 nylon powder, 3-4 of gelatin, 1-3 of ammonium bicarbonate, 6-7 of diatomite, 5-8 of shell powder, and a proper amount of deionized water. Shell powder and diatomite added in the adsorbent has excellent biological property, can improve soil quality, and is high in adsorption efficiency of heavy metal. The prepared adsorbent has excellent adsorption effect on various contaminants, is high in adsorption efficiency, easy to remove, and good in reuse effect, and can greatly improve the soil. The production process is simple, and the material source is wide, so that the adsorbent has great application prospects.

Description

technical field [0001] The invention relates to the field of adsorbents, in particular to an adsorbent capable of adsorbing soil heavy metals and a preparation method thereof. Background technique [0002] Soil is an indispensable resource in people's working life. However, due to the frequent industrial activities of people, most of the heavy metal ions flow into the land, seriously endangering the quality of the soil, and will enter the human body along the food chain, seriously affecting people's health. Heavy metals cannot be degraded by microorganisms, and are easily ingested by organisms and enriched by thousands of times in higher organisms to produce cumulative poisoning. At the same time, due to the hidden, long-term and cumulative characteristics of heavy metal pollution, its treatment It is very difficult and is one of the most difficult pollutants to control. Although various treatment methods such as traditional chemical precipitation method, chelation floccul...
