| Abstract: | A solid phase extraction-high performance liquid chromatographic(SPE-HPLC) method was developed for the determination of phthalic acid esters and their metabolites in human urine.The conditions of pretreatment such as eluent,elution volume and elution velocity were optimized.The optimized conditions were 2 mL of acetonitrile,2 mL of ethyl acetate and 1 mL of ethyl ester-n-hexane(1/19,V/V) at the flow rate of 1 mL/min.Under the optimized conditions,five phthalic acid esters and their monoesters were determin... |
