Abstract
The invention relates to a method for removing chromium from material contg. collagen and chromium, preferably leather contg. chromium, with the use of an extractant, wherein the extractant is a compd. of the formula K+A-, or a mixt. of a compds. of the formula K+A-, where K+ is a cation selected from ammonium, iminium, phosphonium and sulfonium; and A- is an anion selected from phosphate, phosphonate, phosphinate, borate, sulfate, sulfonate, amide, imide, carbene, carboxylate and carbonate, preferably selected from phosphate, phosphonate, phosphinate, thiophosphate, thiophosphonate, and thiophosphinate.
