【摘要】 用荧光分光光度法测定原油中所含阴离子表面活性剂．实验表明，此方法灵敏度高，检出限低，尤其有很强的选择性，适合于复杂体系的测定．对复杂的石油体系经过分离处理后，即可直接测定，相对标准偏差为1．7％，回收率97.1％～101．7％．更多还原

【Abstract】 A fluorometric spectrophotometry was used to determine the content of anionic surfactant in crude oil. It has the advantage of a high sensitivity, low detective llmIts, and a h1gh selectivity. Afte r being separated, the samples can be determined directly. The relative standard deviation is 1. 7%,and the recovery rate is 97. 1 % ~ 101. 7 %.更多还原
