摘　　要：本次研究了在不同铁离子含量以及不同温度条件下的酸洗溶液中双氧水的稳定性;并对潜在的双氧水稳定剂进行了筛选实验。研究结果表明,铁离子含量增加、温度升高都会加速双氧水的分解,从而缩短了酸液的使用寿命,因此需要加入双氧水稳定剂抑制其分解;筛选实验最终提供了7种备选双氧水稳定剂。The stability of H2O2 in aqueous pickling acid was assessed varying ferric content and temperature,and the potential hydrogen peroxide stabilizers were screened in the present study.Results showed that any minor fluctuation of either factors would cause a big attenuation in the life span of H2O2.Thereby,the addition of stabilizers is necessary.The screening experiment finally provides 7 alternative hydrogen peroxide stabilizers.
