Liquid platinum nanoparticles were prepared using a cold plasma jet method within a locally developed system, with a 40-minutesute exposure time, starting from relatively high initial concentrations (40 mg/L). This resulted in nanoparticle sizes ranging from 50 to 80 nm, as determined by a series of tests. These prepared nanoparticles were then used to purify water from inorganic pollutants (a group of heavy metals) via adsorption. The study demonstrated the promising efficiency and effectiveness of the platinum nanoparticles, achieving high purity levels ranging from 66% to 95%, depending on the type of pollutant. The study also showed that purification levels decreased only slightly with increasing temperature. Furthermore, the study confirms that the pollutant treatment was carried out using physical adsorption, a very safe method for treating water pollutants, especially heavy metals. This confirms the effectiveness of relatively large nanoparticles in the safe treatment of inorganic pollutants suspended in water.
