dc.description.abstractIn this study, the potential of mullein leaves (Verbascum thapsus) for the biosorption of Zn(II) and Ni(II) ions from synthetic solutions was investigated. Several factors affecting the biosorption efficiency of mullein leaf powder were investigated, including initial Zn(II) and Ni(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 Zn(II) and Ni(II) before and after biosorption was determined using an optical emission spectrometer with inductively coupled plasma. The maximum biosorption efficiency of 86.46% was observed at a biosorbent dosage of 20 g L−1, pH = 4, contact time 90 min and an initial Zn(II) oncentration of 100 mg L−1. Also, the good biosorption efficiency of 76.51% for Ni(II) ions was achieved at a contact time of 90 minutes. Therefore, mullein was most effective in removing Zn(II) ions from synthetic solutions. Thus, mullein has the potential to be a cost-effective biosorbent for wastewater treatment, but further studies on modified mullein should be conducted.
