dc.description.abstractDefatted Laurus nobilis leaves as a natural biosorbent was first evaluated for elimination of toxic heavy metals such as Pb(II), Cd(II), Zn(II), Cu(II) from aqueous solutions for its wide availability as forest industry waste, in this study. The effects of solution pH, contact time, biosorbent dosage, initial metal ions concentration, ionic strength, humic acid effect, and their competitive effect on the biosorption of lead(II), cadmium(II), Copper(II), and zinc(II) by defatted Laurus nobilis leaves waste (LW) were studied for each metal. The biosorbent was characterized using FT-IR and SEM images. Comparative isotherm and kinetic studies were performed. The sorption of Cd(II) and Zn(II) on LW fitted better in the Freundlich model but Pb(II) and Cu(II) sorption fitted better in the Langmuir model. From the obtained results, the pseudo-second-order kinetic model described the biosorption of cadmium, lead, zinc copper ions the best. The biosorbent showed the maximum biosorption capacities (q(m)) of 96.2, 8.6, 8.7, and 6.0 mg g(-1) for lead, cadmium, zinc, and copper, respectively. These results indicated that LW may be used as an effective and inexpensive heavy metal remediation material. Comparison to previous studies showed that LW is also comparable to (or better than) several other biosorbents.
