摘要
脲醛呋喃树脂中的含氮量,一般采用克氏定氮法,方法繁琐,费时较长,不利于快速分析的要求,本文利用气相色谱法对脲醛呋喃树脂中的氮含量进行分析测定,并建立了测定方法.方法简捷、快速、重现性好,加标回收率在100.8～109.0之间,准确度较高,可很好的满足工业生产中快速分析的要求.
Currently, analysis method of Nitrogen method. It is fussy and long time-taking. In this in Urea-Formalde/Furan Resin is determined by Kjeldahl paper, an analysis method of Nitrogen in Urea-Formalde/ Furan Resin by using gas chromatography is built up. The recovery rate with added specimen for the method is between the 100. 8 and 109.0. This method is convenience and rapidly with good repetition, and especially suitable for the industrious controlling analysis for its conveniency and rapidity.
