铬(Ⅲ)中性配合物催化降解甲基紫的研究

Catalytic Degradation of Methyl Violet with Neutral Coordination Compounds of Cr (Ⅲ)

研究了以铬配合物类污染物为催化剂,在过氧化氢氧化甲基紫模拟废液过程中的催化作用。考察了乙酰丙酮铬、过氧化氢浓度以及pH值等因素对反应的影响。结果表明:试验制得的乙酰丙酮铬,在中性环境下即可显著催化过氧化氢分解氧化甲基紫,溶液脱色率可达96.27%。

Catalysis of a neutral coordination compounds of Cr （ Ⅲ ） was studied in the oxygenation process of methyl violet solution with H2O2. Methyl violet solution was model of azo dyestuff. The effects of catalyst concentrations, H2O2 concentrations and pH values on the reaction were investigated. Results show that the chromium （Ⅲ） acetylacetonate and H2O2 have significant catalytic - oxidation of methyl violet in the neutral condition. Decolorization ratio of methyl violet solution is up to 96.27%.
