“…The biomass used was obtained from the research center in analytical chemistry and physics (CRAPC, Algeria) [20], as a solid waste of the Ammi visnaga extraction and used without further treatment. The biomass was washed repeatedly with distilled water (conductivity 0.5 S·cm -1 and pH 6) until the washing water became colorless, the UV-VIS absorbance spectrum coincides with that of the distilled water, and the electric conductivity and pH remain constant.…”

Abstract:The development of a new clean, easy to handle process with similar efficiency to that of the conventional process is one of the most important challenges in green chemistry investigation. In this study, a new hybrid process was investigated; coupling coagulation-flocculation with adsorption using abundant and natural bioproducts (Chitosan and Ammi visnaga). The Chitosan/Ammi visnaga (coagulation/adsorption) system was studied for its Brilliant Green dye removal capacity. This new technique seems to be a good alternative method for wastewater treatment, showing satisfactory results with high rates of elimination that range around 90 %.

“…Alginate is a natural anionic linear polysaccharide and a water-soluble polymer with abundant free carboxyl and hydroxyl groups. It is an excellent gel-forming candidate that can be used combined with other materials to obtain multi-functional sorbents like beads and membranes [15,16]. Alginate has been widely investigated for the binding of metal ions [17] and for the elaboration of advanced materials such as batteries [18].…”

New high percolating alginate membranes are designed without using sophisticated drying methods: negatively charged alginate reacts with positively charged polyethylenimine (PEI), prior to be crosslinked with glutaraldehyde and air-dried. This is sufficient to obtain a highly macroporous structured membrane. Highly percolating properties of these new A-PEI membranes make the material applicable in natural drainage systems. The high density of amine groups in composite membranes explain their high affinity for anions in acidic solutions. FTIR, SEM-EDX and XPS analysis are used to explore the sorption mechanism. Se(VI) is sorbed through electrostatic attraction between positive amine groups and negative selenium anions; in a second step, bound Se(VI) is reduced by amine and hydroxyl groups in acidic conditions. A-PEI membranes are successfully used for recovering Se(VI) anions at pH 2. The maximum sorption capacity is close to 83 mg Se g −1 ; the sorption isotherm is described by the Sips and Langmuir equations. The membranes are poorly sensitive to flow rate in the range 15-50 mL min −1. The kinetic profiles are fitted by the pseudo-first order rate equation. Solute desorption is operated using NaOH solutions; the sorbent shows a remarkable stability in sorption and desorption properties for a minimum of 4 cycles.
