Özet
Medicinal and aromatic plants which is one of the considerable non-timber forest products in Turkey,especially in the last century have become an important socio-economic values. In this study, Laurusnobilis L. leaves (LNL), an aromatic plant, were used as biosorbent in the treatment process. Theeffects of biosorbent dosage, biosorption time, solution pH, initial zinc and copper ions concentration,humic acid or ionic strength or competitive effects on the biosorption of Zn(II) and Cu(II) by LNL wereinvestigated. The LNL biomass was characterized using SEM and FT-IR spectrum. The non-linearizedand linearized isotherm equations were compared and discussed. Zn(II) and Cu(II) biosorption bettermatched with the Temkin equation and Pseudo second-order kinetic equation successfully definedthe biomass behaviors of both heavy metal ions. Additionally, a single-stage batch bioreactor systemfor heavy metal biosorption based on the best fit non-linear isotherm equation also has beenpresented. It was found that heavy metal uptake was affected by competitive biosorption studies.Finally, these studies showed that the LNL can be used as an environmentally friendly and abundantbiosorbent for removing zinc and copper ions from contaminated waters.
