STUDIES OF CHEMICAL CLEANING ON HISTORICAL LEAD
Original language description
This study has been focused on the evaluation and comparison of the chemical treatments applied (aqueous solutions of CH3COOH (1 %), CH3COONH4 (5/25 %), EDTA (3/5 %), HCl (5/10 %) and ion exchange resin) or possible applicable (H2SO4, Na3PO4 center dot 12H(2)O or KNaC4H4O6 center dot 4H(2)O) to the heritage of lead stored in museums. The evaluation of the different solutions used for chemical treatment on lead samples is based on lead surface changes (colour, morphology, chemical composition) observation and on the impact of the chemical treatments (mass loss and cleaning efficiency). Examination of the lead samples before and after different chemical treatments showed that each of used solutions induced any chemical and/ or physical changes.
