Study on the Experiment of Adsorption Cadmium (II) with Insoluble Starch Xanthate

Abstract:

Insoluble starch xanthate (ISX) is made with the potato starch and can be used for the treatment of cadmium-containing waste water. The performance of treatment and the influence factors with ISX made in this experiment are studied in this paper. It is shown that the removal rate of cadmium ion in wastewater can reach over 96%, when pH value of reaction liquid is 8.0, the adsorption time is 0.5h, and the concentration of cadmium ions in waste water is 30 mg·L^-1.The adsorption mechanism was also discussed. It is shown that ISX promises to be a new treatment adsorbent to wastewater containing the low concentration cadmium. There are some merits with ISX: the smaller recruitment; better processing effect and so on. It is with chemical adsorption that wastewater containing cadmium is treated by insoluble starch xanthate.
