dc.description.abstractIn this study, the potential of mullein leaf (Verbascum Thapsus) as a ground powder for the biosorption of Cu(II) ions from synthetic solutions was examined. Several factors affecting the biosorption efficiency of mullein leaf powder were investigated, including the initial Cu(II) concentration (25–400 mg L−1), solution pH (3–7), contact time (10–120 min.), and biosorbent dosage (2–20 g L−1). The concentration of Cu(II) ions before and after biosorption using inductively coupled plasma optical emission spectrometer was determined. The biosorption efficiency of 58.74% was observed at a biosorbent dosage of 20 g L−1 and an initial Cu(II) concentration of 100 mg L−1. Also, the good biosorption efficiency of 50.74% Cu(II) was reached at a contact time of 90 min. The optimal solution pH was determined to be 4, but the highest removal efficiency of 64.27% for Cu(II) was determined at pH=7. Thus, mullein leaf shows the potential of a cost-effective biosorbent for wastewater treatment, but further investigation of modified mullein will be applied.
