【摘要】 以黑色电气石粉为原料,探讨了电气石粉对Pb2+的吸附作用,研究了吸附时间、用量、粒度、溶液初始浓度以及pH值对吸附的影响。实验结果表明,超细电气石粉对Pb2+有好的吸附效果,电气石粉吸附Pb2+的最佳条件是:吸附时间60min,电气石用量为20g·L-1,pH值为6.5,粒度为48μm。更多还原

【Abstract】 The natural tourmaline has been chosen to be raw material and processed to be superfine powder. The superfine powder of tourmaline is used in the absorption experiment of Pb2+ ion. Factors affecting the absorption of Pb2+ ion in solution, such as time, diameters, quantity of tourmaline, the initial Pb2+ ion concentrations and pH values were studied. The results of experiment indicate the best condition of adsorption of Pb2+ ion is adsorption time 60 minutes, quantity of tourmaline 20 g·L-1, pH 6.5, and diameter 48μm.更多还原
