英文摘要: Abstract(#br)In this work a new procedure for the determination of ultra-trace concentrations of Mo in plants is proposed. Microwave-assisted acid digestion of plants were performed without H 2 O 2 in order to minimize contaminations and obtain lower procedure's blank. Solutions with different HNO 3 concentrations were evaluated to digest the samples and 7 or 1molL −1 HNO 3 solutions led to similar carbon residual contents. Since, analytical blank was a critical issue all samples were microwave-assisted digested using only 5mL of 1molL −1 HNO 3 . For Mo determinations in plant materials an ICP-MS with tandem configuration (ICP-MS/MS) with an octopole...
