【摘要】 本文利用表面活性剂在原子吸收中的增感效应测定了一系列不同平均加成数的十二醇聚氧乙烯醚对镁的增感百分数,并使之与加成数相关,得到了一个线性较好的回归方程式。利用此式可以准确地测定此系列表面活性剂的加成数。更多还原

【Abstract】 Based on the enhancement effect of surfactants in flame atomic absorption speetrometry, enhancement percentages were got for magnesium to a series of dodecanol polyoxyethylene ether with different adduct number. As a result a good-linear regressive expression is obtained. By means of such expression the adduct number of this series of surfactants can be accurately determined.更多还原
