The fundamental characteristics of liquid electrode plasma (LEP), a pulsed source for optical emission spectrometry, were investigated. Two distinct phases observed during the process generation, namely bubble generation and active discharge. ionization efficiency LEP, with Mg as representative analyte, was gauged from ratio II 279.553 nm to I 285.213 found increase about 5% 20% in close-to-lin...

Porous silicon has been prepared using a vapor-etching based technique on a commercial silicon powder. Strong visible emission was observed in all samples. Obtained silicon powder with a thin porous layer at the surface was subjected to a photo-thermal annealing at different temperatures under oxygen atmosphere followed by a chemical treatment. Inductively coupled plasma atomic emission spectro...

Introduction: This study was carried out to determine elements (Li, Na, K, Mg, Ca, Ba, B, Al, Si, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Ag and P) in the Suaeda vermiculata (S. vermiculata) and Suaeda aegyptiaca (S. aegyptiaca) in three different regions of Southern Iran using inductively coupled plasma optical emission spectrometry (ICP-OES) after microwave-assisted acid digestion. Materials and ...

manganese zinc ferrite nanoparticles (mzf nps) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. to improve the colloidal stability of mzf nps for biomedical applications, nps were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (tpp) as crosslinker. the synthesized nps were characterized by x ray diffraction (xrd) analy...

in this work, a novel method is described for the preconcentration of pb2+, cd2+ and zn2+ ions in environmental samples using uniform silanized mesopor (lus-1) functionalized by ethylenediamine groups as a new extractant. the determination of ions is done by inductively coupled plasma optical emission spectrometry (icp-oes). the extraction time and efficiency, ph and amount of adsorbent, minimu...

In the present work, effect of cylindrical configurations sputtering device electrodes on plasma parameters (Debye length, electron temperature, density, frequency) is studied. Also, argon gas pressure discharge properties examined with pressures (0.08, 0.2, 0.4 and 0.6) Torr. The are diagnosed by optical emission spectrometry. spectroscopic method adopted for examining atomic spectra emission....
