IMIDAZOLE SALTS, PREFERABLY A BUFFERED IMIDAZOLIUM REAGENT IS DISCLOSED FOR REMOVING SILVER CHLORIDE (AgC1) FROM A SILVER (Ag) SUBSTRATE BY IONIC DISSOCIATION. THE BUFFERED IMIDAZOLIUM REAGENT REMOVES THE AgC1 LAYER FROM THE Ag SUBSTRATE IN ACCORDANCE WITH THE FOLLOWING REACTION: PREFERABLY, THE IMIDAZOLE COMPOUND IS MIXED WITH ITS BR�NSTED CONJUGATE ACID WITH CHLORIDE COUNTER ION IN APPROPRIATE RATIOS TO ACHIEVE AN ALKALINE SOLUTION WITH pH BETWEEN 8 AND 10 WITH A CONCENTRATION IN THE RANGE OF 0.1 M TO 8 M. PREFERRED SOLVENTS INCLUDE SOLVENT IS ANY ONE OR COMBINATION OF WATER, ETHANOL, METHANOL, TETRAHYDROFURAN, DIMETHYLSULFOXIDE OR ACETONITRILE. THE ARTICLE COMPRISING THE Ag SUBSTRATE WITH AgC1 SURFACE MAY BE IMMERSED IN THE PREPARED SOLUTION WITHOUT AGITATION OR EXTERNAL HEATING. |
