Spectroscopic analysis of zinc plasma produced by alternating and direct current jet

In this study, a system of nonthermal plasma that was operated under atmospheric pressure and was powered by argon gas was employed. The particular plasma properties are affected by changes in the Ar gas flow ranges from 0.5 to 2.5 l/min, product by stream of the plasma jet that is utilized. By using the aforementioned method generated from AC and DC. After placing Ar gas as the cathode, which represents the negative pole, flows toward the anode, which is represented by a tiny metal plate of Zn measuring 6 x 1 cm(2) in size, with a submerged part of 4 cm(2) long, with both types of current employed having a high voltage of 13.5 kV and the frequency of AC was 30 kHz, we measured these variable parameters. It has been shown that when argon flow rises, ionization and plasma glow increase in AC and DC. Thus, when alternating current was utilized, an increase in the plasma properties increased with rose a gas flow ratio of 0.5-2.5 l/min. So the value of electron temperature (T-e) increased from 1.49 to 1.84 eV, electron density (n(e)) also increased from 0.53 x 10(18) to 5.40 x 10(18) cm(-3), f(p) increased from 0.649 x 10(13) to 2.087 x 10(13) Hz, while lambda(D) reduced from 0.116 x 10(<^>-5) to 0.040 x 10(<^>-5) cm. As for when utilizing DC, the plasma parameters rose with an increase in flow ratio of Ar gas of 0.5-2.5 l/min, thus the value of (T-e) elevation of 1.40-1.82 eV, the value of (n(e)) also elevation of 0.34 x 10(18)-5.15 x 10(18) cm(-3), (f(p)) increased of 0.527 x 10(13)-2.037 x 10(13) Hz, while (lambda(D)) reduced of 0.139 x 10(boolean AND-5)-0.041 x 10<^>(-5) cm. The results showed that the AC had a bigger impact on the plasma properties than the DC, as seen by the spectrum peaks identified by a spectrometer.
