Abstract
本发明涉及一种检测硫离子的方法:在1.0×10-6~1.0×10-4mol/L大环化合物A的H2O/CH3OH(3:1,v/v)溶液中,加入1.0×10-7~1.0×10-5mol/L铜离子水溶液,得到铜离子络合物溶液,然后加入待测溶液,如果加入待测溶液后其在538nm处荧光强度增强,则表明待测溶液中硫离子浓度在7.0×10-7mol/L以上,否则待测溶液中硫离子浓度在7.0×10-7mol/L以下;硫离子浓度越大,荧光强度增强越明显。本发明方法光稳定性高,检测限低,重现性好。加入7.0×10-7mol/L的硫离子即可检测到体系荧光强度的变化,在pH=6~10时都具有较好的重现性,因此可用于检测微量硫离子,在真实水样(东湖水)的硫离子检测方面得到实际应用。
Description
技术领域
本发明涉及一种硫离子的检测方法,属于环境保护领域。
背景技术
环境污染直接威胁着人类赖以生存的环境,危害着人类的健康。环境污染的监测及其防治已成为全球性关注的热点之一。硫化物是一种重要的化工原料,含硫废水的排放量正在逐年增加,对环境造成了严重的污染。因此,对SO3 2-、HSO3 -、S2-和H2S等硫化物的分析检测具有重要的意义。目前文献报道检测硫离子S2-的方法主要有:滴定法、分光光度法、电感耦合等离子体、原子发射光谱法、原子荧光光谱法、电化学方法、离子色谱法、荧光分析法和化学发光法等。但滴定法操作繁琐;分光光度法易受其他离子影响;其他几种仪器分析方法也存在抗干扰性差,或价格昂贵等缺点。
发明内容
本发明所要解决的技术问题在于提供一种操作简单且灵敏度高的检测硫离子的方法。该方法所用的物质有较高的光稳定性,检测方法简单,可作为硫离子检测盒,在饮用水,食品,环保等方面得到实际应用。
本发明以大环化合物A
为指示剂,其分子量为508.33,在A的溶液中加入铜离子,与铜离子结合形成络合物,然后加入硫离子,由于铜离子和硫离子的络合能力更强,铜离子和A的络合物解体,释放出A。通过检测添加硫离子前后溶液的荧光光谱强度,进而定量检测硫离子。
本发明采用的技术方案如下:在1.0×10-6~1.0×10-4mol/L大环化合物A的H2O/CH3OH (3:1, v/v)溶液中,加入1.0×10-7~1.0×10-5mol/L铜离子水溶液,得到铜离子络合物溶液,然后加入待测溶液,如果加入待测溶液后在538nm处荧光强度增强,则表明待测溶液中硫离子浓度在7.0×10-7 mol/L以上,否则待测溶液中硫离子浓度在7.0×10-7 mol/L以下;硫离子浓度越大,荧光强度增强越明显。
上述检测硫离子的方法,其特点在于适用于H2O/CH3OH (3:1, v/v, 伯瑞坦-罗比森缓冲溶液, pH = 7.1)溶液体系,光稳定性高,检测限低,重现性好。加入7.0×10-7 mol/L的硫离子即可检测到体系荧光强度的变化,在pH=6~10时都具有较好的重现性,因此可用于做硫离子检测盒,在饮用水,食品,环保等方面得到实际应用。
本发明的优点在于:
1. 本发明中所用的大环化合物A有较高的光稳定性。
2. 本方法检测限低,硫离子的检测限为7.0×10-7 mol/L。
3. 本方法在H2O/CH3OH (3:1, v/v, 伯瑞坦-罗比森缓冲溶液, pH = 7.1)溶液体系中进行,在pH=6~10时都具有较好的重现性。
附图说明
