The Use of Wetting Agents/Fume Suppressants for Minimizing the Atmospheric Emissions from Hard Chromium Electroplating Baths

Abstract

The primary objective of this investigation was to test the effectiveness of a wetting agent/fume suppressant (WA/FS), Fumetrol 140, in suppressing the evolution of hexavalent chromium mist from the surface of a hard chromium electroplating tank. The secondary objective was to evaluate the effect that Fumetrol(trademark) 140 has on the substrates being plated and on the chromium electroplate. Adding Fumetrol 140 to the electroplating tank at a concentration of 0.25 percent significantly changes the surface tension of the liquid, reducing the size of the bubbles formed, and thereby reducing the amount of misting. If chromium emissions can be reduced significantly using WA/FS, there will be a savings in the amount of chromic acid purchased, and the need for APCDs may be minimized or eliminated.
