On-line measurement of Co, Br, Mn in TPA and PTA

Article

Spectroscopy

Terephthalic acid (TPA) and purified terephthalic acid (PTA) are precursors in the making of polyester PET for polyester films, bottle resin, textile fabrics, and specialty chemicals. During production and use of TPA and PTA, the catalysts Co, Br and Mn must be closely monitored to ensure optimum product quality. Rigaku EDXRF Application Note #1539 describes the analysis of concentrations of Co, Br and Mn in TPA and PTA solutions and highlights the performance of the Rigaku NEX OL on-line EDXRF process analyzer.
