摘要
通过研究氢氧化镁吸附处理含As3+模拟废水,考察了振荡反应时间、氢氧化镁用量、反应温度及溶液pH值对As3+去除效果的影响。研究结果表明:氢氧化镁处理含As3+的废水,操作简便,去除率高,可达99%以上。吸附等温线符合Langmuir等温方程,吸附容量为4.04mg/L。
Through the tests on the As^3+ wastewater treatment for As(Ⅲ) removal by magnesium hydroxide,the effects of reaction time,magnesium dosage,pH value and temperature on As(Ⅲ) removal were explored.The experimental results showed that magnesium hydroxide had an excellent performance in the removal of As(Ⅲ) ions from As^3+ wastewater with easy operation and a high removal efficiency(up to 99% above).Its absorption isotherm mode matches well with Langmuir adsorption isotherm function,and its maximum adsorption capacity is 4.04 mg/L.
