- 中文摘要: Liquid-liquid microextraction (LLME) coupled with high performance liquid chromatography (HPLC) for the analysis of palladium is described. The analytes were extracted from a 10.0 mL aqueous sample into organic phase. The extraction time was 20 min. Factors such as pH in aqueous phase, extraction times, and stirring rate were optimised. The method was applied for determination of palladium in mixture samples. The linearity range was from 1.0 to 100 nM and the detection limit was 0.12 nM. Relative standard deviations (%, n = 5) were 0.41 to 0.74. All experiments were carried out at room temperature, 35 ± 0.2 °C.
