过氧化氢酶的棉针织物漂染工艺研究

Catalase for H_2O_2 removal after cotton knits bleaching

氧漂后采用产自嗜热子囊菌的过氧化氢酶去除过氧化氢，对其应用条件进行了研究，得出的最优工艺条件为：过氧化氢酶0．1-0．2g/L，pH值7．0-9．0，温度55℃，处理时间15min。将该工艺与传统工艺作比较，并进行大样试验，结果表明，在棉针织物预处理工艺中应用过氧化氢酶，可以降低成本，减少污染排放。

The applied conditions of catalase treatment for H202 removal after cotton knits bleaching are carried out, the optimum conditions are defined as follows ： treating bleaching bath at pH value 7.0-9.0 and temperature 55℃ for 15 minutes with catalase 0. 1-0. 2 g/L. Compared with traditional process, this new process features better results, lower production cost and less pollution burden.
