Fig. 4From: Burial-induced deterioration in leather: a FTIR-ATR, DSC, TG/DTG, MHT and SEM studyFTIR-ATR spectra for CaC, before and after the soil burial tests. The main absorption bands of collagen (AA, AB, AI, AII and AIII), as well as those corresponding to calcium carbonate (1405 and 874 cm−1), fatliquoring oils/fats (2920, 2850 and 1735 cm−1) and aluminosilicates (1030, 525 and 465 cm−1) are highlightedBack to article page
