摘要
建立了红外光谱法测定无铅汽油中ＭＴＢＥ的方法。运用可调厚度吸收池消除汽油背景所产生的影响。当ＬＩＴＢＥ含量为１．５－１２ｇ／１００ｍｌ时，其误差为０．６－２．９％，对含ＭＴＢＥ为４ｇ／１００ｍｌ的试样分析７次的相对标准偏差为２％。该方法快速、简单，可用于汽油中ＭＴＢＥ的测定。
An infrared spectrophotometric method for determining MTBE in unleaded gasoline isestablished. The effect caused by gasoline background is removed by variable space cell. ForMTBE content of 1.5一12g/100ml,the error is 0.6-2.9%,and the recovery is 97-102%。The RSD for samples containing 4g/100ml of MTBE is 2%(n=7).The method is rapid,simple and can be applied to the determination of MTBE in gasoline.
