Because of the toxic effects of nickel on human health and ecosystem, it is necessary to detect trace nickel in aquatic environments. A new method was proposed for the detection of trace nickel in water, by high performance liquid chromatography with diode array detection (HPLC-DAD) after dispersive liquid-liquid microextraction (DLLME). Dithizone was used as the chelating agent for Ni(II). Several factors influencing the extraction efficiency were studied, and the optimum experimental conditions were achieved. The analytical performance of the method was examined, and it was found that the limit of detection (LOD) was 0.12μg/L and the RSD was 5.3 %. The proposed method was utilized in the determination of nickel in environmental water samples with recoveries of 95.6-106.0 %.
