Es degraden el plàstic i el vidre dels envasos d’aigua amb l’exposició a la llum solar o a la calor?

Abstract

L'objectiu d'aquest treball és presentar una investigació sobre la possible degradació dels envasos de plàstic i de vidre per a aigües minerals, en la qual s'utilitza com a tècnica una volumetria redox per retrocés. Mitjançant aquesta tècnica analítica, es mesura la quantitat de matèria orgànica oxidable que conté una aigua mineral i es comparen les dades obtingudes amb aigües minerals contingudes en envasos de plàstic (polietilè tereftalat, PET) i de vidre exposades a la radiació solar. S'analitza la correlació dels resultats i s'exposen les conclusions.

The aim of this paper is to present a lab investigation about the possible decomposition of plastic and glass packaging of bottled water, by using an inverse redox titration. By this technical analysis we measure the amount of oxidizable organic matter in the bottled water and we compare the data of the water stored in plastic (polyethylene terephthalate, PET) and glass bottles which have been exposed to the sun. We analyze the results and explain our conclusions.
