| Abstract: | A study is made on the performance of carboxymethyl chitosan (CM CTS) in chelating and flocculating and also in releasing copper ions. Under ultimate condition, CM CTS chelates and flocculates Cu 2 up to an efficiency of 99%; moreover, the CM CTS carrying Cu 2 can release Cu 2 slowly and persistently at the medium of weak base. CM CTS can thus be applied to the removal of Cu 2 from wastewater; it can also be applied to the control of red tide by acting as planktonic algaecide. |
