Migration of Minerals and Organic Compounds between Bottled Water and its Plastic Packaging

Abstract

Several studies have shown the bottle’s ingredients have been transported in water, this study aims to investigate experimentally the migration of several minerals from water to PET bottles. A series of water bottles were examined after exposure to extreme conditions of temperature(30, 60 and 90 days)(25, 35 and 45°C).The (AAS) to determine the concentration of Ca, Mg, Na, k, Pb after 90 days showed a significant decrease and increased in the amount of minerals water .the (TOC) concentration increases in mineral water when the temperature increases ,this is confirmed by the FTIR analysis, proving the existence of minerals compounds from the water to PET,and proven by analysis with (XRD).the study proves that the minerals have been successfully implanted into the PET surface, as the (WLI), and hence this result suggests the improvement of the hydrophilic property of the modified PET.
