研究了在空气 -乙炔火焰中 ,阴离子型表面活性剂十二烷基硫酸钠 (SDS)组成的微乳液对铅原子化行为的影响。结果表明 :在 SDS组成的微乳液存在下 ,铅的灵敏度提高了近 6 0 % ,比 SDS胶束存在下灵敏度也提高了 2 0 %。方法用于黄铜和工业废水中铅的测定 ,结果令人满意
The effect of the anionic surfactant sodium dodecyl sulfate (SDS) microemulsion on the atomization behavior of lead in air-acetylene flame was studied. The results showed that the sensitivity of lead increased nearly 60% in the presence of microemulsion consisting of SDS, and its sensitivity increased 20% compared with that of SDS micelles. The method was applied to the determination of lead in brass and industrial wastewater with satisfactory results
