Abstract: The scope of analytical chemistry experiments conducted in higher education institutions tends to be limited, predominantly focusing on traditional analytical methods and the fundamental principles of instruments. Introducing a comprehensive experimental teaching projects can significantly enhance students' abilities in independent exploration, proactive thinking, and problem-solving. This paper presents a detailed design for a comprehensive experiment using nano-titanium dioxide (TiO2) as a photocatalyst for the degradation of phenol pollutants. The scheme involves the principles of photocatalytic degradation and electrochemical monitoring, including the assembly of both the photocatalytic degradation and electrochemical apparatus.

Key words: Analytical chemistry experiment, Photocatalytic degradation, Electrochemical monitoring, Phenol content, Differential pulse voltammetry
