Development and validation of a standard test method for sequential batch extraction of waste with acidic extraction fluid
Subject is characterization of waste materials. Since acid rain is increasingly prevalent throughout the world, a sequential batch extraction method was developed which uses a dilute acid solution as the extraction fluid. A collaborative study was conducted in which the draft method was used to treat a spray dryer waste from a clean coal technology process and a composite mining waste. Effects of filter pore size and digestion vs nondigestion on analytical concentrations in extracts were also studied. Elements determined included Al, Ba, B, Ca, Cr, Si, Na, Sr, Pb, Mg, Mn, Si, Zn. The draft method will be published as ASTM Method D5284-92.
