تحضير جسيمات البلاتين النانوي بالبلازما الباردة لمعالجة الكروم والكادميوم المذابين في الماء

Abstract

Platinum nanoparticles were prepared with a nanoparticle size of less than (30) nanometers in the liquid phase by exposure to cold plasma within a locally manufactured system. The prepared platinum nanoparticles were used to purify water from its inorganic pollutants (cadmium and chromium) by the adsorption method. The study found that there is a promising efficiency and effectiveness of the platinum nanomaterial used, with a purification of cadmium of 79.574% during the first 10 minutes, which decreases to 72.55% after a period of 90 minutes. The purification of chromium was also approximately 71.912% during the first 10 minutes, which decreased to 68.076% after a period of 90 minutes. The study also demonstrated that the purification rates decrease only slightly with increasing temperatures, as the purification of cadmium decreased to the level of 71.563% when the temperature increased to 50 degrees Celsius, and the purification of chromium decreased to the level of 66.888%. When the temperature rises to 50 degrees Celsius, This confirms the effectiveness of platinum nanoparticles prepared with cold plasma for use as a treatment for inorganic pollutants dissolved in their aqueous solutions.
