【Abstract】 In this paper, the methods for preparation of a new chelant-thiocarbamate and removal of Zn 2+ in wastewater by its chelation have been studied. As the result of experiment, the metal-ion chelating agent-thiocarbamate prepared by morpholine with carbon disulfide present an excellent binding force to Zn 2+ in acidic solution. In addition, the process conditions of Zn 2+ removal is determined and showed that the removal rate of Zn 2+ is up to 99% more at pH value ranging from 2 to 6.更多还原
