Total selenium is determined by inductively coupled plasma (ICP) atomic emission using hydride vapor generation. A 1 g sample is wet ashed in a 16 x 150 mm 10 mL volumetric test tube on a programmed heating block with nitric, sulfuric, and perchloric acids at up to 310 degrees C. After treatment with hydrochloric acid, the selenium is reduced by sodium borohydride to hydrogen selenide is a simplified continuous flow manifold. A standard pneumatic nebulizer effects the gas-liquid separation of… CONTINUE READING
