Title
Environmental Chemical Analysis Of Inorganic Ions In Beaver-Dammed Vs. Free-Flowing Sections Of Local Rivers
Description
This project seeks to further the understanding of how river chemistry is altered by beaver dams and aims to measure concentrations of ions in water samples using an analytical separation technique called capillary electrophoresis (CE). Using standard chemicals and calibration curves, the CE method will quantify inorganic ion species. These ions will be analyzed in water samples collected from rivers with beaver ponds interspersed between free-flowing sections. The measured ion concentrations will be compared in free-flowing reaches versus beaver ponds to assess the impact of beaver dams on the in-stream chemical state. To measure this, the CE instrument separates mixtures within a glass capillary and measures each ion individually. A specialized detector is connected to the instrument for measuring separated ions where concentration is a function of conductivity. Positive ions of interest can be separated in under eight minutes, and negative ions of interest can be separated in under six minutes.
