摘要
Abstract
A solid phase extraction coupled with high performance liquid chromatographic (SPE/HPLC) method was established for the determination of 4 kinds of sodium n-alkyl benzene sulfonates in water. The samples were refrigerated and centrifuged, then purified and enriched with MAX complex anion exchange column. Four sodium n-alkyl benzene sulfonates were successfully separated by HPLC using acetonitrile - 100 mmol/L ammonium acetate (73 : 27, by volume) as mobile phase with a flow rate of 1 mL/min, column temperature of 30 ℃, detection wavelength of 225 nm and injection volume of 10 μL. Under the optimal conditions, the calibration curves were linear in the range of 10 -50 mg/L for sodium undecylbenzene sulfonte and sodium N-tridecylbenzene sulfonate with detection limits of 10 mg/L, and 5 -25 mg/L for sodium dodecylbenzene sulphonate and sodium tetradecylbenzene sulfonate with detection limits of 5 mg/L. The spiked recoveries were in the range of 86％ -98％ with relative standard deviations(RSDs) of 2. 9％ -7.4％.关键词
