'邻菲罗啉分光光度法测定微量铁'的实验改进

摘要

"determination of trace iron by Orthophenanthroline Spectrophotometry" occupies an important position in analytical chemistry experiments, but the experimental instruments are simple and the experimental data are easy to be processed. In order to improve the students' practical ability in operation and practice, our school conducted deep discussion on the experimental scheme, redesigned the experimental process, added experimental links and improved existing problems. The improved experiment can help students to improve their interest in independent learning, cultivate students' comprehensive ability of exploring, researching, analyzing and solving problems, and expand the practicability of the experiment.%"邻菲罗啉分光光度法测定微量铁"在分析化学实验中占据重要位置, 但实验仪器单一, 实验数据处理简单.我校从提高学生操作实践动手能力为出发点, 对该实验方案进行了深入讨论后, 重新设计实验过程, 增加实验环节, 改进存在的问题.改进后的实验有助于学生提高自主学习的兴趣, 培养学生探索、研究、分析及解决问题的综合能力, 并拓展了该实验的实用性.
