Abstract:

Over one thousand wastewater dischargers in the US are required to monitor Total Kjeldahl Nitrogen (TKN) and report results to regulatory agencies. The typical TKN procedure consists of heating a mixture for several hours with strong acid and hazardous materials, manually adding strong base to strong acid, followed by a distillation and quantitative measurement of an analyte. TKN is one of the most challenging, dangerous and labor intensive tests performed at wastewater treatment plants.

The primary goal of this project was to develop a green alternative analysis system for TKN that provides comparable analytical results while using significantly less hazardous reagents. In addition, the method must be simple enough for use by current wastewater treatment plant staff with the potential to significantly reduce expenditure of time and analysis costs.
