Axial View

The performance of axial view ICP OES and ICP-MS techniques were compared through the determination of As, Fe, Mn, Pb, Sb and Sn in electrolytic copper. Samples were prepared by two procedures: 1. Total dissolution with 5 % v/v HNO3 and 2. Dissolution with 1.4 % v/v HNO3 plus 2.0 % v/v H2SO4, followed by separation of the Cu by electrodeposition. The methods were applied for the analysis of standard copper solutions, using calibration against aqueous solutions with or without the addition of Cu. The results obtained by the two techniques were similar, but the separation of Cu from the sample matrix proved to be more adequate for practical reasons.

Menilite Shales

Studies of molybdenum and manganese content in topsoil and plants were carried out in the Beskidy Wschodnie (Carpathians) in area of occurrence of menilite shales and the Otryt sandstones. The aim of the study was to evaluate the content of ­molybdenum and manganese in plants and the determination of a bioaccumulation of these two chemical elements in two species of plants (­Trifolium hybridum L. and Plantago major L.). Mo symbols were performed by means of ICP-MS method, and Mn were analyzed by means of ICP-OES method. Result of studies in the Trifolium hybridum L. have shown higher content of Mo in the area of occurence of menilite shales (in leaves – 14 mg/kg) than in the Otryt sandstones (in leaves – 0.30 mg/kg). Most Mn accumulates in leaves (86–257 mg/kg). The bioaccumulate indicator of Mo in individual plant species is different and ranges from 0.13 to 1.13. The highest rate of ­bioaccumulation of molybdenum (1.13) can be observed in Trifolium hybridum L., which inhabits areas of menilite shales.
