扎赉诺尔褐煤对印染废水中的阳离子染料有良好的净化能力。实验证明,它对阳离子染料的交换能力(以mg/g计)为30—50,对不同阳离子染料的吸附序为艳兰RL>嫩黄7GL>红2GL。本文考察了扎赉诺尔褐煤的组成、有效孔径、表面电荷性质以及阳离子染料类型、废水pH值等对吸附的影响。本文指出,阳离子染料在扎赉诺尔褐煤中的有效扩散系数为1×10~(-9)cm~2/s,活化能为4.37kcal/mol。
Zharanuoer lignite dyeing wastewater dyeing cationic dyes have a good ability to purify. Experiments show that its exchange capacity for cationic dyes (in mg / g) is 30-50, for different cationic dye adsorption sequence was blue Lan RL> yellow 7GL> red 2GL. In this paper, the composition, effective pore size, surface charge properties of Zazhu Noel lignite and the effects of cationic dye type and pH value of wastewater on adsorption were investigated. The paper pointed out that the effective diffusion coefficient of cationic dye in Zajianuoer lignite is 1 × 10 -9 cm -2 / s, and the activation energy is 4.37 kcal / mol.
