| Abstract: | Based on a systematic review of the recent studies on heavy metal sorption by sediments,this paper investigates the classifications,primary issues,impact factors and mechanisms of sorption processes Both sorption and speciation are discussed. Various methods have been compared. Deficiencies in the present studies are also indicated As results,perspectives are made on the significance of the study on heavy metal sorption by sediments in hyper concentrated solid liquid systems,which is of potential practical use in environmental and ecological protection in large rivers like the Yellow River |
