Study on adsorption of Methylene Blue by the Modified Kaolin

Abstract:

Using Kaolin as the main raw material,l ultrafine particles modified Kaolin were prepared. Then loading transition metals (copper and zinc), the final modified Kaolin composite photocatalyst was finished. This study used a composite photocatalyst in three main factors photocatalytic oxidation degradation of methylene blue simulated waste Textile Industry water effects. The results showed that the best conditions for simulated wastewater of 100 mL was: methylene blue initial concentration of 40 mg/L, hydrogen peroxide of 0.4 mL, composite photocatalyst of 60 mg, pH 10.21. Under this condition, the chromaticity of methylene blue dropped from 1 600 to 10 after aeration reaction of 120 min, and its removal rate was 99.32%.
