【摘要】 在 pH 为8.3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。通过一系列实验的考察,结果表明,含锌量在0-25μg/25ml 内服从比尔定律,摩尔吸光系数为ε₅₇₀=9.1×10⁴L·mol^-1·cm^-1,线性范围为0-60μg/10ml, 加标回收率为97.21%～101.1%。实验方法简便、灵敏、准确。更多还原

【Abstract】 The micro-fine 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.By studying with experiment,we found that the quantity of the zinc conformed to the beer law in the 0～25μg/25ml,the molar absorption coefficient was ε₅₇₀=9.1×10⁴L·mol^-1·cm^-1,linear range was 0-60μg/10ml,and recoveries of standard addition were 97.21%～101.1%.The method was convenient,sharp and accurate.更多还原
