亚硫酸根离子对固定于聚氯乙烯(PVC)膜中的5,10,15,20-四苯基卟啉(TPP)/t-(2,6-二-氧-异丁基)-β-环糊精(DOB-β-CD)有可逆荧光熄灭作用.据此研制成测定亚硫酸根离子浓度的荧光化学传感器,该传感器敏感膜最佳组成质量分数为:PVC 30.8%,BOS 61.5%,TPP 1.50%,DOB-β-CD 6.20%.在pH=6.5的KOH-KH2PO4 缓冲溶液底液中测定亚硫酸根离子,其线性响应范围为6.22×10-6～3.11×10-4 mol/L,检测限为7.80×10-7 mol/L,其响应时间小于40 s.其它常见阴离子和阳离子不干扰测定.可用于实际样品中亚硫酸根离子含量的测定.
