Insoluble starch xanthate was oxidized with hydrogen peroxide or other oxidants to give insoluble starch xanthide. The effect of temperature, pH and quantity of hydrogen peroxide for product formation was determined. Insoluble starch xanthide was found to be more stable at room temperature than the xanthate; however, it was still effective in removing heavy metal ions from water.
