Review on Contaminated Water Remediation by Nanoscale Zero-Valent Iron

Advances on research of contaminated water remediation by nanoscale zero-valent iron(NZVI) were presented in detail,which accounted for types of contaminants that may be removed,reactive mechanics,and control factors.The NZVI technique can be used to remove several kinds of pollutants such as organic contaminants,inorganic contaminants,and heavy metals in water.The influence factors on contaminated water remediation included dissolved oxygen,pH,initial concentration,NZVI application intensity,NZVI particle size,NZVI co-operation with ultrasonic,and NZVI modification.In addition,special issues on contaminated groundwater remediation by the NZVI remedial technique were discussed pertaining to its practical applications and future research.
