Acid Mine Drainage Project Lab

Acid Mine Drainage Project Lab

This laboratory project uses the context of Acid Mine Drainage to teach concepts important to analytical chemistry and quantitative analysis. Students set up experiments that mimic the process of metal sulfide mineral oxidative dissolution. The experiments explore how the rate of dissolution changes with respect to changes in pH, added oxidizing agents, and oxygen rich or oxygen poor environments. Visible spectroscopy is used to initially measure the concentration of complexed iron in solution. ICP-AES is used to verify the stoichiometry of the arsenopyrite sample. Elemental sulfur determination and the speciation of the aqueous sulfur in the solution can be determined using reverse phase and ion pair high performance liquid chromatography.
Analysis of Phosphorus Concentrations in a Natural Water System

Analysis of Phosphorus Concentrations in a Natural Water System

This guided research project explores the chemistry and impact of phosphorous on a fresh water system of lakes connected by a river in south-central Wisconsin. Students begin this project by comparing the detection limits, matrix effects, and linearity of standard curves of two different spectrophotometric methods for measuring phosphorus. Once the method of choice is validated, students work in groups to design and carry out experiments to explore the chemistry of phosphorus and its impact on the environment.
