Research Interests for Dr. Crackel involve utilizing both molecular and atomic absorption techniques. Some recent student projects include:
- Determination of well-water quality as part of a wellhead protection project.
- Determination of dissolved substances in wastewater as part of a project examining different strategies for wastewater reuse.
- Examination of the efficiency of different lignite/lime mixtures at adsorbing metal ions from aqueous solutions
- Determination of dissolved metal ions in effluent from a trial industrial project.
- Determination of pKa's of acid-base indicators in nonaqueous solvents.
- Determination of formation constants for dimers and aggregates of organic dye molecules in solution.
- Determination of the efficiency of duckweed at lowering the concentrations of dissolved metal ions in waste water.
- Examination of nitrate and phosphate concentrations in wastewater and the changes of those concentrations as functions of treatment and season.
