Textile Wastewater Purification Using an Elaborated Biosorbent Hybrid Material (<i>Luffa–Cylindrica</i>–Zinc Oxide) Assisted by Alternating Current

This paper aims to synthesize hybrid materials with high pollutant-uptake capacity and low costbased based on <i>Luffa cylindrica <i>(</i>L.C<i>)</i></i> and different percentage of Zn<sup>2+</sup> in the presence and absence of alternating current (AC...
