摘要: 合成了一系列长链烷基锍脲类衍生物,用作阴离子选择电极的新型载体,其中以十六烷基丙烯基锍脲苦味酸盐为载体的PVC膜电极性能最佳,线性范围为1.0×10-2~3.9×10-7mol/L,检测下限为2.7×10-7mol/L苦味酸根离子。测试了电极的选择性,并用十八烷基苯基锍脲苦味酸根电极电位滴定小蘖碱。

Abstract: Aseries of long-chain alkylthiouronium derivative were synthesized and used as new type carriers for preparing anion-selective electrodes.The S-hexadecylpropenyl-thiouronium picrate(S-HPTP)showed the best performance among the carriers tested.The electrode based on this carriers compound exhibited linear response range of 1.0×10-2-3.9×10-7mol/L with a detection limit of 2.7×10-7mol/L of picrate ion.The selectivity of electrodes was examined, and the S-octadecylphenylthiouronium picrate(S-OPHTP)electrode was used for potentiometric titration of berberine.

Key words: Alkylthiouronium, PVC membrane electrode, Picric acid, Berberine, Potentiometric titration
