摘　　要：建立了有机化工产品中四丁基溴化铵残留测定的新方法。该法线性范围为0．01～0．10g／L，检出限为0．4mg／L，相对标准偏差为2．4％（0．05g／L，n=11），相关系数为0．998，用于实际样品测定，结果令人满意。A new method for the determination of tetra-butyl ammonium bromide （TBAB） residua in organic chemical products by bromide ion-selective electrode was developed. The linear range of the calibration curve for TBAB was 0. 01 -0. 10 g/L with a correlation coefficient of 0. 998 5. The relative standard deviation was 2.4% （0. 05 g/L, n = 11 ） and the detection limit was 0.4 mg/L. The method has been used to determine TBAB residua in organic chemical products with satisfactory results.
