【摘要】 采用高效液相色谱法对直链烷基苯磺酸钠（ＬＡＳ）同系物的组成进行研究，由ＬＡＳ同系物的百分组成可计算出ＬＡＳ的平均碳峰及平均分子量．方法平均回收率为９８．２％，变异系数为２．６５％．更多还原

【Abstract】 By the study ob linear alkylated sulfonete with high pcrformance liquid chromatography,the composition of LA homoiogue can by known by which the average carbon number and the average molecular weight can be calculated. The methal’s average recoverg is 98. 20%. with a CD 2. 65%.更多还原
