Effects of easily ionisable elements on copper and zinc lines excited in a plasma pencil

Popis výsledku v původním jazyce

The influence of Easily Ionizable Elements (EIE) (chlorides of Na, K, Mg, Ca, Sr and Ba) on the measured spectral lines intensities of copper and zinc excited in a capacitively coupled tubular discharge, known as a plasma pencil, is described. A strong decrease was observed in the dependence on the concentration of the EIE. The decrease is not linear. Addition of NaCl, KCl or BaCl2 causes a steep decrease of the copper or zinc signal for a relatively narrow range of 0.05-0.80 g l(-1). Other EIE, with relatively higher ionization energies, even caused an increase of the Cu I 324.754, 327.396, 510.554 and 578.213 nm and Zn I 213.856, 468.014, 472.216 and 481.053 nm signals. Higher EIE concentrations, up to 4 g l(-1), bring only moderate signal suppression or even a weak signal increase. Atoms of Mg, Ca and Sr likely undergo preferential partial ionization but less than Na, K and Ba so that Cu and Zn atoms do not have enough energy for their ionization but still have enough energy for excitation.
