“…The major part of the investigations has been sacrificed to the most commonly used silver complexant in the classical processing, i.e., thiosulphate (S 2 O 2À 3 ), but alternatives such as thiocyanate, (SCN À ), or some thioethers -like 1,8-dihydroxy-3,6-dithiaoctane (DTO) -have also been studied. A state of the art description of the mechanism and kinetics is found in [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In the frame of the dry processes, completely different silver components like silver behenate (H 43 C 21 COOAg) are currently under investigation.…”
