| 摘 要： | 高岭土吸附剂处理含锰废水中锰离子的实验表明:高岭土的最佳粒度为0.177 mm,pH值控制在7.5～ 8.5间,常温搅拌30 min,吸附剂与水量比为12 g∶1 L,对锰离子质量浓度为100 mg/L的废水的处理效果最好,使锰离子质量浓度由100 mg/L降至0.1 mg/L,锰离子的去除率超过90%,达到GB8978-1996工业废水排放的一级标准.高岭土对锰离子吸附的等温吸附曲线符合Freundlich模型,其吸附机理主要是吸附作用和沉淀作用.

| Abstract: | The removal of Mn~(2+) from Mn wastewater by kaoline adsorbent has been investigated with the batch method. When the best granularity of kaoline is 0.177mm, pH 7.5 to 8.5, the stirring time 30 min, and the ratio of adsorbent to water quality 12 g/L, the experimental results show that the mass density of Mn~(2+) is changed from 100 mg/L to 0.1 mg/L. By this method, Mn wastewater can reach the standard of industrial drain water with the removal ratio of Mn~(2+) more than 90%. The paper suggests that the isothermal adsorption of Mn~(2+) by kaoline agrees with Freundish model, and its chief mechanism is the function of adsorbing and depositing. |
