摘　　要：硫酸亚铁铵制备及测定是一个经典的无机及分析化学类实验。为了增强学生的学习效果、培养学生的环保意识,从教学手段、实验原料、试剂用量以及废弃物处理等四个方面进行分析改进。利用线上线下混合式模式提升了教学质量,采用低污染的原料减少了实验室空气污染,通过试剂用量小量化节约了试剂消耗、降低了成本、减少了废液,采用以废治废的方式减少了环境污染。Preparation and determination of ammonium ferrous sulfate is a classic inorganic and analytical chemistry experiment. To strength the students’ learning effect and environmental awareness, four respects in teaching scheme have been analyzed and improved. By using online/offline mixed mode, the teaching quality has been improved. By using less-poisonous raw materials, the air pollution in the laboratory has been reduced. By using small quantification of reagent dosage, the reagent consumption has been diminished, the cost has been saved, the resource of waste liquid has been decreased. By using waste treatment,environmental pollution has been reduced.
