Contribución al estudio de la extracción química del Fe3+ contaminante de la madera arqueológica subacuática impregnada con polietilenglicol

Due to the large quantity of contamination by Fe in the waterlogged wood and the composites previously processed with poliethilenglycol, PEG , we have thought the possible extraction and formation of complexes Fe-L (L= 2-Phosphonobuta-1,2,4- tricarboxylic acid, (PBTC)) and their effect on (i) structure of the wood, (ii) structure and physiques characteristics of PEG and (iii) post-treatment contamination by Fe coming from atmospheric agents. This work is a project for to study the formation of these complexes and possible modifications in structures.
