摘　　要：化学是一门实验科学,在实验过程中不可避免地会产生各种污染。"绿色化学"既是一种思想观念,又是一种实践,已经成为实现可持续发展的生命和生活价值的必然选择。该文介绍了一种利用铁氧体处理废液中的铬,由分光光度法检测处理前后废液中铬含量的实验方法。该方法简单有效,既增强了学生"绿色化学"的意识,又培养了他们综合与独立进行实验的能力。Chemistry is an experimental science,it will produce many kinds of pollutants in the experimental process inevitably.＂green chemistry＂ is both concept and practice,has become the inevitable choice of valuable life for sustainable development.This article describes a treatment with ferrite of chromium in waste water,and develops a spectrophotometric method for the detection of chromium content in waste water before and after treatment.This method is simple and effective,enhances the students＇ consciousness of ＂green chemistry＂,meanwhile,improves their overall and independent ability to the experiment.
