Abiotic degradation of four phthalic acid esters in aqueous phase under
natural sunlight irradiation
Abiotic degradability of four phthalic acid esters (PAEs) in the aquatic phase was evaluated over a wide pH range 5–9. The PAE
solutions in glass test tubes were placed either in the dark and under the natural sunlight irradiation for evaluating the degradation rate
via hydrolysis or photolysis plus hydrolysis, respectively, at ambient temperature for 140 d from autumn to winter in Osaka, Japan.
The e ciency of abiotic degradation of the PAEs with relatively short alkyl chains, such as butylbenzyl phthalate (BBP) and di-nbutyl
phthalate (DBP), at neutral pH was significantly lower than that in the acidic or alkaline condition. Photolysis was considered
to contribute mainly to the total abiotic degradation at all pH. Neither hydrolysis nor photolysis of di-ethylhexyl phthalate (DEHP)
proceeded significantly at any pH, especially hydrolysis at neutral pH was negligible. On the other hand, the degradation rate of diisononyl
phthalate (DINP) catalyzed mainly by photolysis was much higher than those of the other PAEs, and was almost completely
removed during the experimental period at pH 5 and 9. As a whole, according to the half-life (t1=2) obtained in the experiments, the
abiotic degradability of the PAEs was in the sequence: DINP (32–140 d) > DBP (50–360 d), BBP (58–480 d) > DEHP (390–1600 d)
under sunlight irradiation (via photolysis plus hydrolysis). Although the abiotic degradation rates for BBP, DBP, and DEHP are much
lower than the biodegradation rates reported, the photolysis rate for DINP is comparable to its biodegradation rate in the acidic or
alkaline condition. 相似文献
