Development and Validation of the New EPA Microwave-Assisted Leach Method 3051A

Abstract: An updated, optimized method has been developed to minimize the chemical biases and inefficiencies between two EPA SW-846 alternative leach methods, microwaveassisted Method 3051 and open vessel Method 3050B, for the determination of metals in solid samples. The microwave method is more easily transferred and provides more reproducible leach results, mainly from more precise control of the temperature during the extraction process. Previously, reagent limitations originally placed on Method 3051 did not allow … Show more

“…10 ml of nitric acid was added to each pipe containing soil sample and well closed, then introduced into the microwave oven, and digested using (EPA-3051A) method described by (Link et al, 1998). After samples digestion, extracted samples were transferred quantitatively into 50 ml volumetric flask and the volume was completed by deionized water to the mark.…”

“…The soil samples were microwave digested according to the modified U.S. EPA Method 3052 using a CEM Mars 5 microwave system equipped with HP-500 Plus pressurized digestion vessels and perfluoro alkoxy ethylene liners (Wei et al, 1997;Link et al, 1998). An aliquot of 0.25 g soil was combined with 9.0 ml HNO 3 , 4.0 ml HF and 1.0 ml of de-ionized water in a HP-500 Plus pressurized digestion vessels and PFA (perfluoro alkoxy ethylene) liners for digestion using a CEM Mars 5 microwave system set for the temperature to rise up to 180 AE 5 8C within the 5.5 min and to hold at that temperature for the remaining 9.5 min.…”

“…The digests were diluted with ultrapure water and stored at 4 • C until analysis. Different acid compositions were tested, since Sb is challenging to digest [43,44]. The acid composition finally used for digestion was a mixture of 7.5 mL HNO 3 and 2.5 mL HCl.…”
