Abstract
Glycerol triacetate(triacetin) is the currently used common plasticizer in the making filters from cellulose acetate tow. For the mono acetate filter, the determination of triacetin contents is already established by CORESTA recommended method (No. 59). But unfortunately, the analytical method of triacetin in the activated carbon filter have not reported so far. In this study, it was established the analytical method of carbon filter's triacetin contents at various extraction conditions, bath ratio and internal standard materials. The confidential level appeared above $95\%$ when the extraction time, ISTD material and bath ratio was 3 hours, tripropionin and below 500 mg activated carbon / 50 $m\ell$ ethanol, respectively. Also, in the distribution of triacetin with filter materials in activated carbon filters, the triacetin amount was the most contained in activated carbon. Therefore, this method can be applied to the determination of triacetin contents in the activated carbon filter.
