Title : Removed of Pollutants from aqueous solutions using ecologically acceptable products

Abstract :

In light of the benefits that the Bitter Melon (Momordica charantia) may bring in terms of abundance, this research investigates the possibility of employing the Peels of the Bitter Melon in the manufacture of activated carbon. low cost and product quality. Bitter melon Peels were used to make activated carbon, which was then activated using the HNO3 chemical activation procedure. FT-IR and SEM methods were used to determine surface characteristics. To test the produced carbon's potential to absorb Cr+3, Pb+2 and PPD dyes, they were chosen as important chemical contaminants. The adsorption process was monitored and the elements that influenced it were investigated, including adsorbent mass, temperature, pH, contact time, and initial adsorbed material concentration. It was shown that the adsorption capacity of Cr+3, Pb+2 and dye increased with decreasing temperature. For the adsorbents given, the optimal pH value was (pH= 5 and 6) and the best contact timeframe was (120 min). ΔG, ΔS and ΔH thermodynamic functions were determined. It was observed that the adsorption process is endothermic, since adsorption increases with increasing temperature, and that it is spontaneous. and a rise in randomness, implying that the adsorbent surface is less uniform than the solution. as well as a research study To remove tiny amounts of ions in vast volumes of aqueous solutions, the batch technique and the column method are used.
