| Abstract: | The photocatalytic degradation of polyethylene glycol(PEG) with TiO_(2) nanoparticles as the photocatalyst was investigated.The fact that the amount of CO_(2) and the concentration of residue varied with reaction time indicates that it is a reaction of zero order and the degradation rate of PEG is negatively proportional to the average molecular weight of PEG.TGA and NMR results show that low molecular weight PEG,esters and(other) intermediates were produced during the degradation reaction.PEG was finally mineralized to CO_(2) and(H_2O). |
