XRF法测定SBS中TNPP

Determination of TNPP in SBS Rubber by XRF

以X-射线荧光光谱法定量测定SBS橡胶中TNPP抗氧化剂(通过测定P元素),是对轻基体(C、H)中轻元素 (P)的测定,有一定的难度。但经过我们实际探索,在基体稳定,干扰杂质很少的情况下,测量效果令人满意,经实际试样和标准试样检测,本法可用于实际试样分析,特别适用于中控分析,具有简便快捷,准确可靠的优点。

It is difficult that a quantitate analytical method for the determination of antioxidant TNPP in SBS rubber by XRF spectrum. The analytical method determinated light element (P) from light matrix(C. H). But through the actual explore, the effects of measurement were satisfying if it was in the situation of steady matrix and low interference impurity. Through the determination of actual samples and standard samples, the method can be used as a simple and fast, nice and credible way to analyse the actual samp...
