This study is aimed at development of an analytical method for the determination of heavy metals and arsenicin waste material from barite recovery by dual view inductively coupled plasma optical emission spectrometry (ICP-OES) after wet digestion. Aquaregia open digestion method was used for sample preparation. A soil certified reference material was used to study the efficiency of wet digestion procedure applied to sterile dump material. The sensitivity, accuracy, and precision of the method were determined. The achieved detection limits are: Arsenic (As) 0.80; Copper (Cu) 0.29; Lead (Pb) 0.29; Zink (Zn) 0.30; Cadmium (Cd) 0.11; Chromium (Cr) 0.09; Nickel (Ni) 0.02, mg.kg ⁻¹ .The developed method is applied for the determination of hazardous metals and arsenic in sterile dump material from closed barite mine in the region of Tarnita-Suceava, Romania.
If you don't have microwave I recommend USEPA 6010A, but if you have try USEPA 3015A
Depending on which heavy metals are to be determined, however you can, simply, try acid digestion with concentrated nitric acid. After complete dissolution, the excess acid is expelled with boiling. The final clear digest is appropriately diluted to fit the measurements with ICP.
