Despite waste minimization efforts, mercury-contaminated waste is still generated with the current test method. Several possible replacements for mercurous nitrate have been identified. The objectives of the mercurous nitrate replacement tests are:
• Provides timely results.
• To be less hazardous to personnel and the environment.
• To be implemented in current production environments, preferably using existing facilities.
An accelerated ammonia vapor test has been successfully demonstrated and is being scaled up to accommodate facility test quantities. An accelerated ammoniacal copper sulfate has also been successfully demonstrated. The proposed replacement test(s) will be tested alongside the current mercurous nitrate test method to ensure that results correlate strongly. The proposed replacement tests will be less hazardous to the environment and personnel, will reduce the cost of lot acceptance testing, and will comply with increasingly stringent environmental regulatory requirements.
