Abstract |
Nickel emissions from electroplating operations are of concern to EPA. Therefore, EPA has determined that it would be useful and important to obtain actual nickel emission data from nickel plating operations using EPA-Approved testing methods (both Method 29 and Method 306A). The five nickel plating processes tested in this project were: Electroless Nickel, Rack Watts Nickel, Barrel Watts Nickel, Nickel Sulfamate, and Woods Nickel Strike Plating. In addition, by modifying some of the operating parameters (i.e. surface tension, agitation methods, etc.), EPA can determine the impact of these operational changes on nickel emissions. The stack testing was conducted over a two year span from June of 2004 through January of 2006. |
