The properties, applications of organobentonites in enviromental protection were described. The mechanisms and rules of organic pollutants to organobentonites from water were reviewed. The applications of organobentonites in wasterwater treatment and remendiation of polluted environment were also forecasted.The sorption behaviors for dual-cation organobentonites to sorb aniline, p-nitrophenol, 2,4-dichlorophenol from water were investigated. The results suggested that organic pollutant distribution coefficients (K |
