Caracterització de siloxans adsorbits en carbó activat provinent d’EDARs

This paper aims to identify which compounds are adsorbed in the activated carbon used in wastewater treatment plants using GC-MS. It also aims to study what interactions occur in the adsorption process and how these interactions affect the siloxanes that are adsorbed. According to these purposes, an analytical method for chromatographic analysis using GC-MS has been developed and several activated carbons have been analyzed to identify and quantify the compounds adsorbed. A suitable method for quantification of siloxanes in THF solution has been made. The results obtained show that siloxanes adsorbed in chemically activated carbons undergoes polymerization reactions besides physical adsorption. Several siloxanes were identified and characterized together with some organic volatile compounds such as toluene and limonene
