摘要
在微乳液 (十六烷基三甲基溴化铵 /正丁醇 /正庚烷 /水 )介质中 ,进行了锌 ( ) -锌试剂显色体系激光热透镜光谱法 ( TLS)测定锌的研究 ,并与在水介质中该体系锌的测定进行了比较。结果表明 ,以微乳液为介质进行锌的测定 ,具有灵敏度高 ,线性范围宽 ,检测下限低 ,抗干扰能力强等优点。应用该方法进行了镀锌废液中锌的测定 ,结果满意。
The cationic microemulsion(CTMAB/ n C 4H 9OH/ n C 7H 16 /H 2O) as a medium on the determination of Zn 2+ was investigated by TLS(Thermal Lens Spectrometry).It is shown that the sensitivity of determination and the linear range in microemulsion solution was stronger than that in water solution,and it had more effective ability against some interference ions.The method has been applied in the determination of Zn 2+ in wastewater with a satisfactory result.
