摘　　要：用溶胶—凝胶法制备一种以溶胶凝胶为载体的溴离子选择电极.该电极有良好的能斯特响应,电极的响应范围为5.2×10-6～1.0×10-1mol/L,斜率为53.5 mV/dec,检测下限为4.5×10-6mol/L.电极响应快、体积小,稳定性和重现性好.电极用作测定药物,其结果令人满意.Abstract： The sol-gel technique has a great future for immobilization. This paper reports the sol-gel as a cartier for bromine ion selective electrode. The electrode showed Nemst response for bromine ion in the linear rage of 1.0×10^-1- 5.2 ×10^-6mol/L with a slope of 53.5 mV/del . The detection limit is 4.5×10^-6 mol/L. The electrode has the advantages of fast response, small size, good stability and reproducibility. The electrode was used to determine the drug. The results are satisfactory.
