Study on adsorption of acid dyes wastewater by organic clay
摘要
Abstract
The adsorption of acid dye wastewater with organic clay was studied by static tests.Meanwhile,organic clay was characterized by means of XRD.The effect of pH, dosage of organic clay and concentration of wastewater on the adsorption was studied, and the adsorption mechanism was discussed.The optimal condition of adsorption of acid dyes was: dosage of organic clay was 1.5 g.Under the optimal condition, when the initial CODα was 3 578 mg/L, the adsorption of organic clay was 91.80 mg/g, the removal of CODα was 76.97%.Under the solvating effect and distributional effect, the adsorption isotherm of acid dyes wastewater with organic clay is S type.Organic clay had better absorption ability with acid dyes under acid condition.Organic clay still had absorption ability after repeated absorption of acid dyes wastewater, and the adsorption amount of pollutant gradually decreased with the adsorption times increasing.关键词
