Abstract : The objective was to evaluate commercially available noncyanide metal strippers for replacement of cyanide metal strippers used by the Air Force. Laboratory tests were conducted on coupons made from materials commonly subjected to cyanide stripping solutions. These included samples of plate metals, basis metals, and masking materials. The stripping rates for plate metals, basis metals, and masking materials. and solvation properties of masking materials were determined in solutions of noncyanide strippers obtained from commercial sources. In addition, the solutions were tested for biodegradability under conditions similar to those in the Air Force Industrial Wastewater Treatment Plants (IWTPs). The information obtained from these tests indicates that several noncyanide strippers will be technically acceptable as replacements for cyanide formulations currently used by the Air Force. Keywords: Strippers; Cyanide; Noncyanide; Electroplating; Biodegradable; Industrial wastewater; Hazardous waste minimization.
