王昌益 %A 和海清 %J 高分子学报 %D 1980 %I %X A simple, rapid and accurate method is presented for the micro-analysis of fluorine element in fluoropolymers. Fluoropolymers and CF3-containing organic compounds are quantitatively decomposed and titrated. The titration reaction is a stoichiometric one and has a sharp end-point. The absolute error of this method is ±0.3%. Interferences of SO4=, PO4(?), AsO2- (or AsO4(?)) and CO3(?) can be eliminated by a simple procedure. This method is suitable for microanalysis of F element in C, H, 0, N, Cl Br, I, Si, S,P,As-containing fluoropolymers. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=6579068328FE643F&jid=15971983683C7643EE80F1CE621DEB60&aid=813AEE596564780C&yid=E56875464B1C0EC1&iid=94C357A881DFC066&sid=F637763636425CAF&eid=7737D2F848706113&journal_id=1000-3304&journal_name=高分子学报&referenced_num=1&reference_num=0
