摘要
本文报道用流动注射法(FIA)快速测定三元复合驱油体系中的溶解氧,讨论了各种物质对测定的干扰情况。本方法最小检测量为80μg/L,相对标准偏差为2.6％,并与测定溶解氧的经典的碘量法进行了对比,结果令人满意。
A new flow injection analysis method for the fast determination of dissolved oxygen in three components flooding oil system containing alkali-surfactant-polymer is proposed , based on the reaction of dissolved oxygen with the leuco-base of methylene blue to give a soluble blue oxidation product of which the absorbance is direct proportional to the oxygen concentration. There is no interference among many ions and compounds in three components flooding oil system. The detection limit and relative standard deviation of the method are 80μg/L and 2. 6%, respectively. Comparing with the convenient indometric method(Winkler method), the results are satisfactory.
