الوصف: | Polyethylene terephthalate bottles containing natural spring water were used to study the leaching effect of carbonyl compounds after one year storage under real conditions of exposure. Ultraviolet-B and ultraviolet-A spectra of direct sunlight were acquired during the experiment. Leaching of acetone, acetaldehyde, and formaldehyde reached steady state after 210 days of outdoor storage, with the following concentrations: 434 ± 22, 345 ± 18, and 94 ± 5 µg/L, respectively. The increase due to sunlight exposure in comparison with laboratory storage in the dark was around 10%, 16%, and 36%. The leaching process of all three carbonyl compounds was found to follow the first-order kinetics. Photo-degradation of Polyethylene terephthalate bottles and the appearance of carboxyl end-groups were followed by attenuated total reflectance infrared spectra. After 313 days of storage under direct sunlight, new peaks appeared in the regions of 1770–1920 cm−1 and 1685–1490 cm−1. Cations, anions, total dissolved solids, pH,... |
