Starch xanthate was synthesized from corn starch and CS 2 under alkaline condition. The effects of catalyst dosage, CS 2 dosage and reaction temperature on sulfur content and copper ion removal rate were studied by single factor experiments, and the structure of the product was characterized by FTIR, SEM and XRD. The results showed that the optimum synthetic condition of ISX was NaOH dosage 16 mL, CS 2 dosage 2.5 mL, reaction temperature 35 °C and reaction time 2 h. The sulfur content of ISX synthesized under this condition was 7.54%, the removal rate of copper ion was 90.5%, and the adsorption capacity of ISX was 90.0 mg/g.
