钢渣对直接大红4BE染料的脱色性能
Decolorization of Direct Scarlet 4BE by steel slag
摘要
Abstract
The factors that influenced the decolorization rate of Direct Scarlet 4BE by steel slag and adsorption mechanism were studied.It was conducted in the coagu-flocculation test mixer by stir adsorption.The results show that the steel slag has a good removal efficiency when initial pH=7.0,initial concentration of Direct Scarlet is 100 mg/L,particle size of steel slag is 100~120 mesh,the dosage of steel slag is 10.0 g,mass ratio of dye and steel slag is 2∶ 1(mg/g)and rotational speed is 200 r/min.The decolorization rate can reach 97.14% after 100 min and the wastewater can reach classⅠof chroma standard in discharge standard of water pollutants for dyeing and finishing of textile industry.The mechanism of the process mainly has fast physical adsorption,ligand exchange of OH-and pigment anion and the effect of coagulation and sedimentation.关键词
