响应面法优化过氧化氢酶去除漂白残留过氧化氢工艺的研究

Study on removal of residual hydrogen peroxide from bleaching process with catalase by response surface methodology

采用过氧化氢酶去除棉针织物煮漂后残留的过氧化氢残液,用响应面分析法确定最适过氧化氢酶去除棉针织物上残留过氧化氢工艺为:过氧化氢酶用量0.144 g/L、处理时间16 min、处理温度27℃、p H=7、浴比1∶15.在此条件下,过氧化氢去除率提高到97.69%.

The residual hydrogen peroxide solution was removed from bleaching process of cotton knitted fabric by catalase. The optimum conditions for removal the residual hydrogen peroxide of cotton knitted fabric with catalase by response surface methodology were as follows： amount of catalase 0.144 g/L, enzyme processing time 16 rain, temperature 27 ℃, pH=7, bath ratio 1 ： 15. Under the optimum conditions, the removal rate of residual hydrogen peroxide Was increased to 97.69%.
