甲基橙的光谱电化学研究

The electrochemical behavior and the mechanism of methyl orange on tin oxide film electrode were studied by thin layer spectroelectrochemistry. The final products of the reduction of methyl orange are N, N - dimethylphenylenediamine and sodium aminophenyl sulfonate. There are two steps of hydrolytic reactions following the oxidation of the electrogenerated N, N-dimethylphenylenediamine in solution.

基于建构主义的技工化学实验教学模式的构建与实践

探索基于建构主义理论的教学模式在技工化学分析实验操作技能训练中的应用,并做了与传统教学模式的教学对照实验。
