WebOct 20, 2024 · Microbial-induced carbonate precipitation (MICP), an economical and effective method, was used to block the in situ migration of Cd2+in the soil profile. The results of the laboratory experiments showed that the maximum Cd2+adsorption capacity of the soil exposed to MICP (8.92 mg/g) was higher than that of soil without MICP (7.12 mg/g). WebMICP is a promising technique that can be used for containment of various contaminants and heavy metals. The availability of lead in soil may reduced by its chelation with the MICP product, which is the mechanism responsible for lead immobilization. [56] MICP can be also applied to achieve sequestration of heavy metals and radionuclides.
