This study focuses on formulating an undergraduate laboratory experience on catalyzed decay kinetics of common Food, Drug & Cosmetic (FD&C) dyes. The catalyst, Fe<sup>III</sup>-TAML (Tetra-Amido Macrocyclic Ligand), activates hydrogen peroxide and has shown effectiveness in the degradation of a variety of pollutants. This provides an excellent teaching model for undergraduate laboratories that can be beneficial in the study of fundamental chemical concepts. The experimental parameters are designed to allow students to study kinetics and determine rate laws under various reaction conditions. By adjusting the peroxide concentration, students can be also introduced to the Michaelis-Menten mechanism. In addition to serving as a didactic kinetics experiment, this lab also introduces concepts of green chemistry and allows for further discussion. The concepts of catalysis and degradation are themes that can be directly connected to principles of green chemistry.
