Description

The optimum conditions in HPLC separations using columns packed with polymer gels were investigated for analyzing and characterizing directly various organic pollutants in water without complicated pretreatment. Experimental results showed that polystyrene gel column was unsuitable for direct analyses of water samples. Direct analyses of various organic compounds in water could be achieved on polyacrylester and polyhydroxystyrene columns by using 0.02 mol L−1 phosphoric acid and acetonitrile (85:15) as a mobile phase. At 40 °C, these systems of column and mobile phase gave values of height equivalent to a theoretical plate ranging from approximately 0.10 to 0.25 mm and retention times ranging from approximately 8 to 60 min for various compounds in water. Separation characteristics of these polymer column systems were discussed by taking into account solubilities, functional groups, aromaticities, or molecular weights of organic compounds in water. Furthermore, several wastewaters and their treated waters were directly analyzed for examples.
