摘　　要：制备一种以四（十二烷基）碘化铵为定域体试剂，利用二氧化钛溶胶凝胶技术研制的磺胺嘧啶电极．该电极以溶胶凝胶为载体，线性范围为4．Ox10^-6-1．0x10^-2mol／L，检测下限为2．0×10^-6mol／L，平均斜率为61．0mV／dec．适宜的pH范围为1．1-5．3．电极用作测定药物含量及其回收率测定，结果令人满意．A novel ion selective electrode for determination of sulfadiazine was prepared based on the titanium dioxide sol-gel technique with tetra-dodecyl ammonium iodide as an active material. The sol-gel technique has a great future for immobilization. This paper reports the sol-gel as a carrier for sulfadiazine selective electrode. The linear range of 1.0x10-2 -4.0x10-6mol/L a de- tection limit of 2.0x 10-6 mol/L at pH 1.1 -5.3 and a slope of 61.0 mV/dec for sulfadiazine were obtained. The electrode was used to determine the drug content and recovery. The results are satisfactory.
