Also, we propose several ways to reform experimental teaching, and provide references to other experimental courses. Keywords: Self-Design Experiment; Spectrophotometer; Spectrum; High Pressure Mercury Lamp; Deuterium Lamp  Introduction Laboratory courses are a crucial component of a National Quality Course (NQC)—Environmental Chemistry. In this re-search group, we believe that the construction and reform of this subject is important, and our core task is to develop teach-ing quality, improve students’ experimental abilities, promote motivation and enthusiasm, inspire a spirit of scientific explora-tion and creativity, thus enabling students to conduct scientific research and solve practical problems. The aim of the NQC is to settle various problems regarding the construction of course content, and we as NQC instructors manage and design the laboratory teaching ourselves, and in-creasingly self-design comprehensive experiments. We offer opportunities for students to gain knowledge, develop their re-search abilities, and enhance their independence. Meanwhile, we reform the laboratory teaching methods, and encourage dis-cussion and an
