Analysis of Highly Mineralized Aqueous Solutions by ICP-AES
Environmental Inductively Coupled Plasma (ICP) methods, such as EPA 200.7 or SW846 Method 6010, expect that samples will be fairly dilute without an overabundance of dissolved constituents (less than 2000 ppm Total Dissolved Solids). Laboratories running mine-impacted waters, such as acid rock drainage from exposed copper tailings, or mineral digests of a “waste” sample (that is actually ore) may run Method 200.7 or 6010 as written. They do this to remain in compliance, but in doing so may get incorrect...
