ABSTRACT:
Disclosed is an aqueous solution of a chromium salt, in which the oxalic acid content is 8% by weight or less relative to chromium. In the aqueous solution of the chromium salt, the total organic carbon content is 4% by weight or less relative to chromium. The chromium salt is preferably a chromium chloride, a chromium phosphate, or a chromium nitrate. The chromium chloride preferably contains a basic chromium chloride represented by the composition formula Cr(OH)xCly(wherein 0<x≦2, 1≦y<3, and x+y=3). The chromium phosphate is preferably one represented by the composition formula Cr(H3−3
PO4)n(wherein n is a number satisfying 2≦n≦3). The chromium nitrate is preferably a basic chromium nitrate represented by the composition formula Cr(OH)x(NO3)y(wherein 0<x≦2, 1≦y<3, and x+y=3).
