分析化学实验中含铬废水的处理

Treatment of chromium-containing wastewater in analytical chemistry experiment

对分析化学实验中产生的含铬废水,选择沉淀法与阴离子交换树脂法相结合的方法进行处理,使处理后废水的铬含量远小于国家排放标准。将其引入学生的实验课与毕业论文选题中,以增强学生的环保意识与解决实际问题的能力。

Through experiment this paper research chromium - containing wastewater from analytical chemistry experiment using the precipitation method and anion exchange resin method, the concentration of chromium in treated wastewater is much less than national discharge standard. And student will be asked to consider this in their experiment course and graduation thesis, in order to improve their consciousness of environmental protection and ability to solve practical problem.
