| Abstract: | In this paper,wastewater which contains lead ion was treated with starch xanthate.Some factors which affect the removal of lead ion such as the amount of starch xanthate,the pH value of solution and the reaction time were studied.The results showed that the removal rate of lead increased with the rising of the pH value,the best removal rate is up to 99.92%,and the residual concentration of lead ion is less than 0.10mg/L.The removal effect is remarkable and the heavy metal can be recycled without secondary pollution. |
