摘　　要：Water-insoluble bagasse xanthates were prepared by xanthation of alkalified celluloses by treating bagasse with chromium hydroxide reauction effluent.The removel of nickel from both test solutions and electroplating industrial wastewater samples with BX was investigated. The process was studied taking into account such parameters as pH of water, precipitation time, xanthate dosage and storage time of BX. These products were found to be highly efficient in removing nickel. The residual con centration of nickel after treatment can be reduced to a value Of the ordor of 0. 01mg·1￣-1.
