Analysis of copper content in the poly(phenylene oxide) production process streams
Polimery 2018, No 4, 290
Results of copper determination in process streams coming from the poly(phenylene oxide) (PPO) production by precipitation polymerization of 2,6-dimethylphenol using the copper(II) salt as a co-catalyst have been presented. A microwave-assisted sample preparation analytical procedure for the determination of copper in stream samples from the organic solvents (methanol or ethanol, toluene) and the catalyst components [copper(II) ions, morpholine] recovery nodes using a modern Milestone Ultra WAVE digestion system combined with the FAAS technique has been proposed. The method is useful for quick and efficient determination of copper in liquid samples with organic (methanol/ethanol – toluene, morpholine) mixtures and aqueous-organic matrix.
