摘要
研究了超微粉碎米糠的用量、溶液温度、镉离子浓度、溶液pH值和吸附时间等影响因子对超微粉碎米糠吸附水中Cd性能的影响。实验结果表明,超微粉碎米糠对水中Cd具有很好的吸附效果,吸附率达90%以上。其最佳吸附条件为:超微粉碎米糠用量5g/L,温度30℃,pH=3,Cd质量浓度低于20mg/L,吸附时间30m in。
The factors that effect absorption of cadmium in wastewater include the solution temperature and cadmium concentration, pH value and absorption time. The results show that super micro - milling rice bran indicates excellent absorption effects on cadmium in wastewater with more than 90% absorption rate. The best absorption conditions are 5g/L of dosage of super micro - milling rice bran and 30℃ of temperature and 3 of pH value and 30 minutes with less than 20mg/L of cadmium concentration.
