| Abstract | A novel method for separating and enriching trace phthalate esters (PAEs) in river water by solvent sublation and their determination by high-performance liquid chromatography (HPLC) has been developed. The optimal conditions of the solvent sublation were obtained, that is n-hexane as the sublation solvent, pH 7 of the solution, a nitrogen flow rate of 70 mL min... and sublation time of 70 min. The floated product under the optimal conditions was determined by HPLC. In the process of HPLC analysis, an Eclipse XDB-C18 chromatographic column was used, and mobile phase consisted of acetonitrile and water using gradient elution, and the flow rate was 1.00 mL min.... The proposed method was applied to determine eight PAEs in the river water from Fangshan District, Beijing; the recoveries ranged from 76.9 to 120.4%, RSD values from 2.63 to 9.71%, and limit of detection values ranged from 0.001 (for diethyl phthalate and butyl benzyl phthalate) to 0.225 ...gL... (for dimethyl phthalate and dicyclohexyl phthalate). (ProQuest: ... denotes formulae/symbols omitted.) |
