摘　　要：针对目前高校开展的分析化学实验内容单一、项目陈旧等问题,将创新综合性实验教学项目引入到课堂教学中,能够增强学生独立思考、主动探索和解决问题的能力。因此,我们设计了包括样品制备、分析测试、数据处理及结果对比等步骤的实验教学方案。该实验以分光光度法测定Ni、Mo金属含量为目的,通过对工业油品加氢脱硫催化剂(Ni-Mo/γ-Al_(2)O_(3))进行制备及金属含量测定,使学生既能了解负载型催化剂制备的常规实验方法,又能掌握分光光度法定量分析技术。Aiming at addressing the problems of single-content and obsolete projects in university-level analytical chemistry,introducing innovative and comprehensive experimental projects into teaching classrooms can enhance students’ability to explore and solve problems independently.Therefore,we designed an experimental teaching scheme that includes sample preparation,characterization and evaluation,as well as data processing and result comparison.The purpose of the experiment is to determine the contents of Ni and Mo in industrial oil hydrodesulfurization catalysts(in this case,Ni-Mo/γ-Al_(2)O_(3) catalysts)using spectrophotometry.The goals are to enable students to understand the fundamentals of conventional supported catalyst preparation and master the quantitative analysis procedure of spectrophotometry.
