以煤岩组分浮选分离为目标,研究了pH值、表面活性剂以及无机调整剂对不同煤岩组分Zeta电位的影响及其规律性.结果表明,改变体系pH值、添加阳离子表面活性剂CTAB及无机调整剂AlCl3都有利于增大镜煤与丝炭的表面电性差异,且pH值和药剂量对神府煤岩组分Ze-ta电位的影响具有协同作用.%In order to separate the macerals in Shenfu coal, the influence of pH values, surfactants and inorganic modifier on the surface electrical properties of macerals were investigated. The results show that changing the pH values of the system, addition of the cationic surfactant CTAB and inorganic modifier A1C13 to the system are beneficial to increase the differences between the vitrain and fusain. The influence of pH values and agent concentration on maceral zeta potential is synergistic.
