Application Note: Mercury Determination In Sorbent Trap Material

The Environmental Protection Agency (EPA) issued a federal rule to permanently cap and reduce mercury emissions from coal-fired power plants. In order to comply with the EPA mercury emission standard, the power industry is required to determine the amount of mercury emitted from their power plants. One technique that may be utilized is described in EPA 40 CFR Part 75 Appendix K, and allows for sampling of the stack effluent and off-line analysis of mercury retained by sorbent traps (iodidetreated, activated carbon).
