| 摘 要： | 研究了电气石的粒度、用量及环境条件（pH值、温度、搅动情况）对水中Cu^2 吸附的影响，分析了电气石对含Cu^2 废水的净化原理。电气石本身的静电场对Cu^2 的吸附作用使Cu^2 与表面羟基的离解产物OH^-在电气石表面上发生反应，形成沉淀，从而达到净化目的。

| Abstract: | This paper deals with the mechanism of applying tourmaline to purifying Cu 2+_doped waste water based on the study of absorbing Cu 2+ ion by tourmaline in water. Factors affecting the absorption of Cu 2+ ion in solution, such as diameters, quantity of tourmaline particles, and experimental conditions (pH value, temperature, stirring situation) are studied. The purifying mechanism of tourmaline lies in the existence of electrostatic field around tourmaline particles, which attracts Cu 2+ ion and causes Cu 2+ to combine with OH -, the dissociation product of hydroxyl at the surface of tourmaline, thus forming precipitation on tourmaline and attaining the aim of purification. |
