Bisphenol a catalyst pdf
WebBisphenol A polycarbonate (BPA-PC) is an important engineering plastic with unique properties. However, it has some inherent flaws like chemical resistance toward greases and oils. Hence, to improve the chemical resistance the effect of small amounts of polybutylene terephthalate (PBT) functionalized with allyl glycidyl epoxy (AGE) were evaluated. WebDec 1, 2024 · In this study, a biochar catalyst derived from waste preserved wood (PWB) was prepared for the degradation of bisphenol A (BPA) via peroxymonosulfate (PMS) activation. The PWB exhibited...
