Abstract:

An attempt was made to simulate XAD-8 isolates of Orange County groundwater and Biscayne Aquifer groundwater using mixtures of single ligands. Mixtures of catechol, glycine, phthalic acid and salicylic acid were used to simulate potentiometric and complexometric titrations. Concentrations used for the mixtures were based on carboxylic acidity, dissolved organic carbon, and assumed values for phenolic acidity and nitrogen content. Potentiometric titrations were reproduced with mixtures of the ligands however, complexometric titrations at pH 6.2 and pH 7.5 could not be duplicated. Organic matter leaches from plants and soil matter enters natural systems and become dissolved organic carbon DOC or particulate organic carbon POC. JES
