WaleI-. W/r llexa\~alcnt ct1romium. iin alkali m&d permanganate providing at least 760 ppm permanganate. alkali metal, or aluminum halide providing Ltt least 100 ppm of halide. and 3 pH of 1.0 to 4.0.
Jan. 13, 1998
A process l’or the removal and inhibition of Irnchinp of lead contained within the brass material of plumbing fixtures by immersing in an aqueous leaching solution containing nitric acid and one or several inhibitors selected from the group ot’ block copolymers of polyethylene glycols. propylene oxide and ethylene oxide. tluorocarbon YurfBctants, and polyols.
