Total recoverable metals are defined as the concentrations of metals in an unfiltered aqueous sample treated with hot nitric and hydrochloric acids according to EPA Method 3005. The method is suitable for the preparation of digestates for the FLAA and ICP-AES analysis. This procedure is known to produce low recoveries of silver due to precipitation and of antimony due to evaporation.
