The micro-zine of the lubrication oil was determined by using CTMAB in borax-hydrochloric acid cushion solution whose pH value was 8.3,and setting up a quickly analytical method which determined micro-zine in lubrication oil.

• 在pH为8.；3的硼砂-盐酸缓冲溶液中；应用水杨基荧光酮(SAF)-溴化十六烷基三甲氨(CTMAB)显色体系测定润滑油中的微量元素锌；建立测定润滑油中微量锌的快速分析方法。
