摘要
油罐车是否污染喷气燃料,使喷气燃料的银片腐蚀不合格,主要是由油罐车内壁残留的元素S含量所决定。研究发现,罐车内壁锈粉与罐底残存油中元素S含量呈一定的相关性。本文采用汞滴法,利用汞滴在不同含量的元素S中变色时间不同这一性质,快速测定残存油中的元素S含量范围,从而可知罐车内壁是否吸附有过高的元素S,为准确判断油罐车是否污染喷气燃料提供重要的依据。
Whether the silver strip of jet fuel in oil tank was polluted or not is determined by content ot sulfur. The content of sulfur tank bottom and inside wall rust powder had relativity. The content of sulfur was fast determined by mercury drop method which is different content determines the time of color change. This method provided important basis to determine the pollution of oil tank.
