Effect of Cd2+, Cr3+, Cu2+, Al3+, Co2+ ions on the chemical recycling of poly(ethylene terephthalate) in sulphuric acid

[摘要] Poly(ethylene terephthalate) has been hydrolyzed in sulphuric acid using various additives (Cd2+, Cr3+, Cu2+, Al3+, Co2+) in order to investigate their influence on the reaction conversion. The addition of 5 μM of the single ions does...
