目前高校开展的分析化学实验内容较单一，忽视了培养学生对分析全过程的质量保证和质量控制的能力，缺乏对学生探究能力和综合素质的培养。因此，我们设计了一项包含样品的制备、方法的适用性验证、样品前处理、上机分析和数据处理以及实验过程中如何做好质量保证和质量控制等步骤的分析化学综合实验。该实验以大米为试样，指导学生利用石墨炉原子吸收光谱仪器、基于外标法定量、综合运用多种质量保证和质量控制措施对大米中的镉含量进行准确测定。本实验涉及到分析的全过程，综合性较强，既有利于学生将所学的理论知识应用于实践分析中，也有利于提高学生分析问题和解决问题的能力，能更好地培养学生的探究性思维。本实验易于操作，实验过程安全性较高，且能在8学时内完成，适合高校中分析化学教研组以小组制、项目化的形式向本科二、三年级的学生开设。
