Presentation on the XXVI Encontro Nacional da Sociedade Portuguesa de Química

Natércia Teixeira will be presenting on the 24th of July of 2019 our lastest work on iberian medieval iron-gall inks.

All the extracts and inks were analyzed in threefold by HPLC-ESI-MS and HPLC-DAD. HPLC-ESI-MS allowed the identification of the phenolic compounds present both in extracts and inks. HPLC-DAD allowed the quantification of these compounds. The main goals of this work were: 1) to identify and quantify the major phenolic compounds present in the gall extracts and evaluate its variation by the addition of an iron sulphate salt and gum arabic when producing the iron-gall inks; 2) to identify and quantify the identify and quantify the effect of each additive on each tested recipe.
