摘要
主要研究用淀粉黄原酸盐(ISX)处理含镉废水,探讨了淀粉黄原酸盐用量、反应液pH值、反应时间、废水浓度等因素对镉离子去除率的影响。结果表明:当处理20 mL含Cd2+浓度为40 mg/L废水时,pH值为8,ISX用量为0.3 g,处理时间为15 m in,废水中镉的去除率可达97%。
Researching using the starch xanthate to remove cadmium ions from electroplating waste water. The effect of the amount of starch xanthate, pH value of reaction liquid, reaction time and concentration of the waste water on the removal efficiency of cadmium ions are investigated. It is found that when pH value of reaction liquid is 8, the concentration of cadmium is 40 mg/L, the adsorption time is 15 min at room temperature, and the ISX dosage is 0.3 g, when the treatment quantity of waste water containing cadmium ions is 20 mL, the cadmium ions removal efficiency may reach 97%.
