在十二烷基磺酸钠(SLS)存在条件下,基于KI和Hg(Ⅱ)形成[HgI4]2-络阴离子后与四丙基溴化铵(TPAB)结合形成离子缔合物使共振光散射(RLS)信号强度明显增强,建立了运用共振光散射技术测定水样中汞含量的新方法。研究了四丙基溴化铵-碘化钾-汞体系的共振光谱特征,在393nm处体系的散射光强度最大.在最佳实验条件下,体系的共振光散射强度与Hg(II)浓度在0.05~1.0μg.mL-1范围内呈良好的线性关系。用此方法测定合成水样中的Hg(II),操作简便快速,回收率在96.17%~101.67%之间,结果令人满意.

A new method has been developed for the determination of Mercury based on the enhanced resonance light scattering(RLS)intensity resulting from the complex formed by 2-and tet rapropyl ammonium bromide(TPAB) in the presence of sodium dodecyl sulphate(SLS).The characteristics of RLS spectra of ion-association complex have been investigated and the maximum RLS peaks at 393 nm.Under the optimum condition,there is a good linear relationship between the RLS and the concent ration of Mercury in the range of 0.05~1.0μg/ mL.This method is simple and speedy.It is successfully applied to determine Mercury in synthesized sample and the results are satisfactory,with the recovery between 96.17%~101.67%.
