生物柴油中甘油含量测定方法的研究

A study about analysis of glycerin content in biodiesel

对生物柴油中甘油含量的分析方法进行了研究,通过几种试验验证,该方法具有很高的回收率(95%～105%),准确可行,可测定的甘油浓度范围广(0.90%～99.81%),并且既适用于生物柴油中甘油含量的测定,又适用于原料中甘油含量的测定,具有通用性。

This paper gives a study on analytical method of glycerin content by chemical methods in biodiesel. We get these conclusions by the experiments the reclamation of this method is very high (95%～105%), it can be used in wide glycerin content (0.90%～99.81%) and not only in biodiesels but also in raw materials, these indicate that it is exact, feasible and universal.
