Inductively coupled plasma optical emission spectrometry (ICP-OES) is widely used in trace-metal analysis. However, the behavior of this hot, ionized gas and effects on analyte excitation and ionization is not fully understood. To obtain sufficient information on the characteristics of plasma, two previous approaches, Abel inversion and tomography, have been used. Major drawbacks of these appro...
In this paper, the resonance optical absorption method, is used to measure the Cu atoms number density in different power levels of power supply. Atoms are sputtered from a Cu target during plasma magnetron sputtering deposition. For the light source, a commercial Cu hollow cathode lamp is used. For measurement of gas temperature, a small percentage of N2 is added to the gas mixture and the gas...
In this article, inductively coupled plasma mass-spectrometry (ICP-MS) and optical-emission spectrometry (ICP-OES) were used for the development of an analytical procedure analysis waste Sm-Co magnets. Experimental parameters related to microwave digestion processes acid concentrations optimized. Microwave was carried out in mixtures HF, HCl, HNO3 H2SO4. The complete dissolution samples occurre...
