Additional Concentration

The conditions for the preconcentration of carbamate, phenylurea and triazine pesticides from water samples were investigated, and optimized methods were developed for the determination of the pesticide groups. Bakerbond spe C18 cartridges were used for the preconcentration. The preconcentrated carbamate and phenylurea pesticides were eluted from the cartridges with acetone, whereas the triazine herbicides were eluted with chloroform. After additional concentration by evaporation, the eluates were analyzed by RC-HPLC on an AQUAPORE RP-300 column using a methanol-water mixture as the mobile phase.
