摘要:... Finally, inorganic mercury was directly determined by CVG-ICP-MS, while microwave-assisted oxidation with H 2 O 2 was needed for total mercury detection. The concentration of organic mercury, mainly methylmercury, was obtained by difference of total mercury and inorganic mer...

摘要:... Following microwave-assisted digestion of the sorbent, mercury was quantified by continuous-flow CV-AAS. Factors affecting the sorption and desorption of Hg(II) were optimized. The calibration plot is linear in the 0.2–50.0 μg L−1 Hg(II)) concentration rang...

摘要:... Pretreatment was carried out using agitation in an incubator shaker and microwave digestion. Subsequently, DNA from bones was isolated by the classical organic phenol–chloroform extraction and silica-based spin columns. Decalcification buffer for total demineralization w...

摘要:... The advent of microwave-assisted digestion led to new devices that have allowed the development of new procedures based on diluted solutions of nitric acid and more recently the use of oxygen as a reagent. No doubts oxygen has played a major role in most dry and wet digestion...

摘要:... A microwave-assisted digestion has been developed for sample treatment, which has been evaluated using isotope dilution analysis (IDA) of Cr, Se, Cd, Ba and Pb. Evaluation of the analytical method in terms of sensitivity (LOQ between 0.002 and 1 mg kg−1), acc...

摘要:... In comparison with microwave-assisted digestion, the proposed method is simple, requires short time and eliminates total sample dissolution before analysis. Suspension medium was optimized for each analyte to obtain quantitative recoveries from fish tissue samples without...
