Analysis of copper content in the poly(phenylene oxide) production process streams

Polimery 2018, No 4, 290


DOI: dx.doi.org/10.14314/polimery.2018.4.6

Summary

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.
