摘要
介绍了电气石在环境工程中应用的研究现状,并以内蒙赤峰黑电气石为吸附剂,系统研究了吸附时间、温度、用量、pH值、金属离子初始浓度等条件对电气石吸附Cu2+、Pb2+、Zn2+效果的影响;用Langmuir和Freundlich吸附等温线描述了吸附剂的吸附特性;探讨了电气石在实际废水中对重金属离子的吸附规律;最后研究了电气石的红外发射特性。
The current situation in the research of application tourmaline to environmental engineering was introduced. With the black tourmaline from Chifeng in Inner Mongolia as absorbent, the paper systematically researched the effect of adsorption time, temperature, consumption, pH value, initial density of metal ion on ad- sorption of Cu^2＋ , Pb^2＋ , Zn^2＋. Following that the paper described the adsorption characteristics of the absorbent through using Langmuir and Freundlich adsorption equal temperature line, and discussed the adsorption law of tourmaline on the heavy metal ions in real waste water. And finally, the paper studied the infrared emission characteristic of the tourmaline.
