AbstractThe current research aims to use plants as substituent of chemical additives in the elimination of pollutants, therefore making polluting industries environmentally friendly. In the present work, the potential use of Stipa tenacissima (cultivated in the dry region of North Africa) in the removal of H2S in aqueous solution was investigated. The obtained experimental results showed successful elimination of H2S through reaction with Stipa tenacissima fibers in an alkaline aqueous medium. The effect of Stipa tenacissima’s mass, temperature ranging 20–60 °C, and aeration on sulfide removal efficiency was examined. The study clearly revealed that the aeration processes enhanced the removal reaction, and the increase in temperature gave a better removal rate with an optimal mass ratio of Stipa tenacissima of 0.1 g to eliminate 0.2 mg H2S.
