Remediation effect of inorganic-organic composite materials on Cd contaminated soil
field test method was used to analyze and study the remediation effect of inorganic-organic compound ma-terials on Cd contaminated soil.The inorganic materials are mainly sepiolite,montmorillonite and bone meal,while the organic materials mainly include fungus residue and chicken manure.The study found that the inorganic-organic compound material can effectively improve the pH value of soil contaminated with Cd,and the pH value can be in-creased by 0.96 units at most.And when different contaminated soils were tested,Cd levels dropped.Among them,bone meal+organic materials had the best effect on soil remediation activities of catalase and urease.There-fore,the use of inorganic-organic compound materials can achieve the expected effect on soil restoration of Cd,which can be popularized and applied in the current process of soil restoration of Cd pollution.
