Abstract
The 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 H
2
S in aqueous solution was investigated. The obtained experimental results showed successful elimination of H
2
S 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 H
2
S.
