目的 为保证包装用水基型胶粘剂产品质量安全，研究建立一种包装用水基型胶粘剂中硼酸/硼砂的ICP-MS快速测定方法。方法 样品用稀硝酸溶液涡旋震荡，使水基型胶粘剂完全分散破乳，取上层溶液经高速离心后用ICP-MS进行测定，优化了萃取硝酸溶液浓度和涡旋震荡萃取时间。结果 获得的最佳萃取硝酸溶液体积分数为15%，涡旋震荡萃取时间为20 min。方法的检出限为9.43 μg/kg，样品加标回收率为97.0%~103.0%，相对标准偏差小于3.0%（n=6）。结论 建立的方法操作简便快速，灵敏度高，结果准确可靠，可适合于包装用水基型胶粘剂中硼酸/硼砂含量的快速测定；实际检测样品中有少量硼酸/硼砂残留，但均符合GB 9685规定的最大迁移限量（6 mg/kg）的要求。

The paper aims to develop an analytical method inductively coupled plasma (ICP-MS) for rapid determin-ing boric acid or borax in water-based adhesive to guarantee the quality of water-based adhesives for packaging. The wa-ter-based adhesives were completely dispersed and demulsified with nitric acid solution by the vortex oscillation. The solution was centrifuged at high speed and determined by ICP-MS, and the concentration of extracting nitric acid solution and the extracting time of vortex oscillation were optimized. The optimum concentration of nitric acid solution was 15% (volume fraction) and the extraction time of vortex oscillation was 20 minutes. The results showed that the detection limit of boron acid was 9.43 μg/kg. The recoveries were in the range of 97.0% to 103.0% and the relative standard deviation was 3.0% (n=6). This method is simple, rapid and accurate, and suitable for rapid determination of boric acid or borax in water-based adhesive for packaging. A small amount of boric acid/borax residual is found in the actual samples, but they all meet the requirement of specific migration limit of 6 mg/kg in GB 9685.
