Biosorbent and Its Applications

Biosorbents,such as microorganisms or biomaterials,are capable of uptake of heavy metal ions,nondegradable or hazardous organic compounds in water solution,which can remove pollutants from wastewater or other solutions.In addition,biosorbents can be used in the process of mining and wastewater treatment for precious metal recovery.This review reports the research activities and developing trend of biosorbents;examines the principle of biosorption and various biosorbents;discusses the pretreatment method and immobilization technology of biosorbents.The application areas about it were summarized,and it has advised to the research in the future.
