Tamarix aphylla Leaves Synthesized Biochar Loaded Fe doped MgO Nanocomposites for Dye Pollutants Removal from Water

Water pollution due to the Synthetic dyes is a serious issue now a days. The Chromophoric groups found in dye molecules are the source of color pollution. There are many conventional methods that was adopted to eradicate them. This study examined the synthesis of Fe-doped MgO biochar nanocomposites for the efficient degradation of methyl orange dye from wastewater. Biochar is a solid carbon-rich substance which was obtained from the leaves of Tamarix aphylla plant using slow pyrolysis method. After preparation of biochar further synthesis of Fe doped MgO nanocomposites was done by using of iron chloride as a source of iron and then mixed with previously prepared biochar . Afterwards the mixture is stirred for 30 minutes to facilitate reduction and formation of desired material. To settle down the material we allowed the mixture to stand for thirty minutes. Later on the settled material was isolated using decantation and then stored in sealed container. Later on various analytical parameters such as dye concentration, adsorbent dosage, contact time, pH, temperature, photocatalytic degradation, zeta potential and their effect dye on degradation of methyl orange was examined. The evaluation of adsorption rate by changing all the factors one by one helped us to draw valuable conclusions regarding to the efficiency of prepared material .The purity, particle size and morphology of a composite was investigated by using Fourier transform infrared Spectroscopy , X ray diffraction technique , scanning electron microscopy and Transmission electron microscopy respectively.
