TREATMENT OF CR (III) CONTENT IN WATER USING COLD ATMOSPHERIC PLASMA TECHNIQUE

Contamination of water with heavy metals is considered to be one of the important problems in the worlds. Scientist made many experiments and researches in order to remove these pollutants as minimum as possible. In the present work, a new method to remove one of the heavy metals element which is Cr (III) from the water was done. Standard samples were prepared in the lab and diluted to achieve samples of known concentrations (0.1, 0.05, 0.025, 0.02, and 0.01) mg/L. Each sample was exposed to a cold plasma source for different exposure times. Cr (III) concentration was examined after each exposure time (5 sec – 10 min) step 5 sec. Results show that removing heavy metals elements to about 90% - 95% from water samples in a little period of time. From these results and by comparison with other methods, the cold atmospheric plasma jet is a more effective method for the removal of heavy metals than other methods.
