Production of New Adsorbent from Mango residues Collected in the Urban Community of Mamou

Abstract

Activated coal obtained from mango residues is an alternative for the valorisation of these wastes for applications. This work focuses on the production of a new adsorbent from mango residues collected in the urban common of Mamou (Republic of Guinea) by chemical activation with potassium hydroxide. To do this, the different rates: humidity, cinders, volatile matter, fixed carbon et iodine indices before activation and after activation at 400°C and 700°C were determined which are: (6.28%; 0.97%; 73.80%; 25.23%) respectively. The best indices were found in powdered activated coal compared to grain activated coal for the concentrations used. This study can be an alternative bio-adsorbent for the urban community of Mamou in water treatment.
