Abstract
Dissolved phosphorus is a nutrient of concern in the Great Lakes basin, particularly in the western basin of Lake Erie. Dissolved reactive P (DRP) is largely responsible for the formation of harmful algal blooms and the continued eutrophic status of the Lake. Attempts to mitigate P losses into the Lake have met with mixed success. Sorption and desorption of P from river sediments has been identified as a potential driver of lags between implementation of best management practices and observable results. Adsorption and desorption occur when any change in the chemical equilibrium of the phosphorus concentration is made, such as the appearance of competing forms of P that bind to sediments. Our research aims to characterize the sorption behavior of different types of phosphate esters and other P-bearing compounds. This semester, we have been identifying interferences and analytical obstacles to quantitative study of binding constants, with an aim to better characterize the existing assay protocols.
