摘要
烟用水基胶样品采用硝酸（65＋35）和过氧化氢进行程序控制升温微波消解，用电感耦合等离子体质谱法测定样品溶液中硼酸的含量。采用B作为测量同位素来消除质谱干扰。方法的检出限（3S／N）为0．12tzg·L-1。方法用于烟用水基胶的分析。用标准加入法测得其回收率在102％～109％之间，测定值的相对标准偏差（n=6）小于5％。
Sample of water-based glue was treated with a mixture ofHNO： （65@35） and H202 by microwave assisted sample digestion under programmed temperature elevation, and content of boric acid in the sample solution was determined by ICP-MS. MS interference was eliminated by choosing u B as isotope in the determination. Value of detection limit （3S/N） found was 0. 12 g L 1. The proposed method was applied in the analysis of sample of water-based glue. Values of recovery found by standard addition method were in the range of 102%-109%, with RSD＇s （n=6） less than 5.
