| Abstract: | Water-Insoluble Bagasse Xanthate(IBX)has been prepared byxanthation of alkali-cellulose which was obtained by treating bagasse withalkali.The precipitation of lead with IBX has been investigated.Thisproduct is a new ion-exchanger.It was found to be highly efficent inremoving lead.After wastewaters were treated,the residual concentrationsof lead were reduced to values of less than 0.1mg/L. pH conditions donot significantly affect the process. The high removal of lead can beobtained within 15 min.The required xanthate dosages are not completely inaccordance with stoichometric quantities.The products containing magnesiumions of the effective amounts have a good room-temperature stability. |
