Study on decolorization of wastewater containing acid dye by laccase
摘要
Abstract
Laccase DENILITE Ⅱ was used for catalytic decolorization of acid dye. For the 0.1 g/L acid blue 80 dye, the decolorization process optimized by single factor was as fol ows: DENILITE Ⅱ 1.0 g/L, pH=6, temperature 60 ℃ and treatment time 7 min. Under the above conditions, the decolorization of acid blue 80 dye was 77%. Moreover, there was great influence of sodium sulfate and sodium dodecyl benzene sulpho⁃nate on the enzyme activity, but had little effect at low concentrations. Through response surface optimization and regression analysis, the theoretics maximum decolorization was 79.4% under the fol owing conditions: ac⁃id blue 80 dye 0.1 g/L, DENILITEⅡ1.2 g/L, temperature 70℃, pH=7, treatment time 7 min.关键词
