A new selective and sensitive spectrofluorimetric method in non-ionic microemulsion for the determination of trace Ni(II) in water has been developed. This method is based on the quenching of fluorescence of Triton X-100/n-C5H11OH/n-C9H20/H2O microemulsion system due to the formation of complex Ni(II)-SAF-Triton X-100. The results show that there is a linear relationship in the rang of 0.5-2.5 ng.25 mL-1 for Ni(II). The sensitivity in microemulsion is higher than that in micelle. Satisfactory results are obtained for Ni(II) in water sample.
已开发出一种用于测定水中痕量镍（II）的新型非离子微乳液选择性灵敏荧光分光光度法。该方法基于镍（II）-SAF-Triton X-100络合物的形成导致Triton X-100/正戊醇/正壬烷/水微乳液体系荧光猝灭。结果表明，镍（II）在0.5 - 2.5 ng·25 mL⁻¹范围内呈线性关系。微乳液中的灵敏度高于胶束中的灵敏度。对水样中的镍（II）获得了满意的结果。
