建立共振光散射测定水中痕量萘酚新方法.萘酚在稀硫酸介质中,与溴酸钾、吖啶橙发生反应形成聚集离子,产生共振散射光谱.,导致共振光散射显著增强,据此建立了共振光散射测定痕量萘酚新方法.α-萘酚和β-萘酚具有共同的光谱性质和行为,其最大的共振光散射峰468.0nm;方法线性范围1.41×10~(-7)-2.80×10~(-5)mol/L,相关系数r=0.9996,检出限4.22×10~(-8)mol/L,水样分析相对标准偏差为4.8%-7.3%,平均回收率为95.7%.方法灵敏、简单、快速,样品测定结果满意.

A method was proposed for the determination of trace naphthols was established based on the reaction of naphthols with potassium bromate and acridine orange（AO） to form ion-association complexes in the dilute H2SO4 medium,which produced of resonance light scattering （RLS） spectra and resulted in the great enhancement of RLS.β-naphthol and β-naphthol had common character of spectroscopy and action.The greateat peak of RLS was at 468nm.The method had good linear relatively in proportion of naphthols in the range of 1.41×10-7—2.80×10-5mol...
