自制硫酸亚铁胺晶体,并将其作为芬顿反应的催化剂,降解几种常见指示剂。实验表明,指示剂的脱色、降解效果良好。建议将这2个实验列入高校的分析化学实验课程中,并将硫酸亚铁胺用于滴定分析实验后指示剂的降解。
In this paper,home-made(NH4)2Fe(SO4)2·6H2O crystal acted as an efficient Fenton regent to degrade several indicators of the analytical chemistry experiments.The results revealed that the indicators could be effectively degraded and decolorized.Therefore,we suggested that the experiment should be added to analytical chemistry experiments in order to degrade the toxic indicators.
