[The sensitized reaction of non-ionic microemulsion on the determination of trace Ni(II) by fluorescence quenching method with salicyfluorone].
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.
