摘　　要：建立了一个高效液相色谱方法，对邻氨基苯甲醚及其同分异构体进行分离，从而避免了其同分异构体对邻氨基苯甲醚含量测定的干扰，防止出现假阻性结果。该方法的加标回收率为73.65%-83.69%（皮革制品）和74.89%-84.85%（纺织品），精密度实验RSD均小于5%，d S/N＝3的条件下，检出限分别为0.3mg/kg（邻氨基苯甲醚）、0.3mg/kg（间氨基苯甲醚）和0.5mg/kg（对氨基苯甲醚）。该方法简便快捷，定量准确，有效地解决了禁用偶氨染料测试中邻氨基苯甲醚的假阳性结果问题。An effective HPLC method was established to separate o-anisidine and its isomers such as m-anisidine and p-anisidine, in order to avoid false positive result in the analysis of o-anisidine which was susceptible to interference of its isomers. The spiked recoverics varied from 73.65% to 83.69% for leather products, from 74.89% to 84.85% for textiles. The relative standard deviation （RSD） of precision experiments was all less than 5%. At the condition of S/N =3, the detection limit was 0.3, 0.3 and 0.5mg/kg for o-anisidine, m-anisidine and p-anisidine, respectively. The proposed method was simple, rapid and accurate, and the problem of false positive result of o-anisidine in the determination of banned azo dyes was effectively solved.
