Elimination of the Organic Pollutants by Biochar from Pomegranate Powder Activated by Phosphoric Acid in an Aqueous Solution: Influence of the Stirring Speed
Synopsis
The protection and preservation of the environment are the pillars of sustainable development, which currently constitutes a major challenge for the future of man and the planet. Currently, humanity is faced with an alarming increase in the pollution of the natural environment by various organic or inorganic materials: endocrine disruptors, pesticides, dyes... The purpose of this study is to explore the possibility of recovering a natural waste, (pomegranate powder) to eliminate Bisphenol A (BPA) and Methylene Blue (MB), in an aqueous solution, and improve the retention capacity by calcination and activation by phosphoric acid (H3PO4). The material produced was analyzed by different techniques: ash rate, humidity rate, iodine index, methylene blue index, the pH of the zero charges, infrared spectroscopy (IR), scanning electron microscopy (SEM) and fluorescence spectroscopy (FRX). The material was evaluated in the treatment of BPA and MB, and the parameter of stirring speed was studied. The results obtained showed that the elimination efficiency was about 98% for BPA and MB. So, we can replace expensive adsorbent materials with materials prepared from natural biomass for the treatment of wastewater and the elimination of Bisphenol A and Methylene blue.
