Effects of easily ionisable elements on copper and zinc lines excited in a plasma pencil
Original language description
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.
