Background: evaluating the efficacy of plasma generator systems in the extraction
of metal ions from aqueous solutions, as well as their application in the desalination
of water, under varying time intervals and concentrations.
Aim: decrease the concentration of dissolved metal ions in water, thereby
enhancing water quality and improving key parameters related to water hygiene.
Methodology: This study involved the design and construction of two distinct
plasma generation systems: one based on aeration and the other employing direct
radiation methods. The plasma generated by these two systems was assessed as
being consistent and appropriate for use. To investigate the removal of lead ions, a
standard solution with a concentration of 1000 ppm was prepared, from which
various lower concentrations were derived. A NaCl solution was utilized to
evaluate the removal of sodium ions from seawater and brine, while a MnCl2
solution was employed to assess the removal of manganese ions. Following the
experiments, the samples were analyzed using X-ray diffraction (XRD), scanning
electron microscopy (SEM), atomic absorption spectroscopy, a spectrophotometer,
an electrical conductivity (EC) meter, and a pH meter.
Findings: The experimental results indicate that the plasma generator system
utilizing the aeration method effectively eliminates 30% of lead ions present in
water within a 15-minute. In contrast, the plasma generator system employing the
direct radiation method achieves a 50% reduction in the electrical conductivity
(EC) of water while simultaneously facilitating the evaporation of soluble salts.
This process also leads to an increase in nitrate and nitrite levels, accompanied by
a decrease in pH.
Conclusion: the results indicate that plasma-generating systems demonstrate
effective performance in the removal of water-soluble ions. Notably, these systems
facilitate the precipitation or evaporation of metal ions through advanced oxidation
processes. Furthermore, the enhance
