摘要 通过紫外光谱分析方法,考察了双β-二酮分子1,2-二(3-硫醚基-2,4-戊二酮基)乙烷对Cd(Ⅱ)离子的识别性能和萃取性能,并用该分子对合成水样中Cd(Ⅱ)离子的含量进行了浓度分析实验。结果表明,1,2-二(3-硫醚基-2,4-戊二酮基)乙烷对Cd(Ⅱ)离子具有良好的识别性能和优良的萃取性,两者形成的是1∶1型配合物,并且1,2-二(3-硫醚基-2,4-戊二酮基)乙烷可以对水样中Cd(Ⅱ)离子含量进行分析测定。 The ion recognition and extraction properties of 1,2-bis( 3-thio-2,4-pentanedionate) ethane with Cd( Ⅱ) ion had been investigated by the ultraviolet spectrophotometry,and followed by the discussions on the concentration of Cd( Ⅱ) ion determination in synthesis water samples.The results showed that 1,2-bis( 3-thio-2,4-pentanedionate) ethane had good ion recognition and extraction properties for Cd( Ⅱ) ion,their coordination binding stoichiometry was 1 ∶ 1,and the concentration of Cd( Ⅱ) ion in water samples was also analyzed with 1,2-bis( 3-thio-2,4-pentanedionate) ethane as the recongnition receptor.
