TI  - Quaternary Adsorption Effect of Nickel (II), Antimony (III), Manganese (II) and Copper (II) onto Living Two Green Microalgae
AB  - This study aimed to investigate Ni, Sb, Mn and Cu adsorption from aqueous solution by Chlorellaand Scenedesmus algae. The competitive adsorption efficiency of nickel (Ni2+), antimony (Sb3+), manganese(Mn2+) and copper (Cu2+) onto two living microalgae strains was studied from multi-metal aqueous solution for24h incubation time. After exposure, chlorophyll a-b, total carbohydrate and Atomic force microscopy (AFM)imaging were performed. Then adsorption isotherms models of metal ions were determined based on Langmuirand Freundlich isotherms. The adsorption capacity in multi-metal system was determined 6.47 mgg-1 forantimony, 5.96 mgg-1 for manganese, 28.57 mgg-1 for copperand 10.71 mgg-1 for nickel (Cu>Ni>Sb>Mn) byChlorella respectively, whereas, and 10.82 mg g-1 for antimony, 7.07 mgg-1 for manganese, 27.09 mgg-1 forcopper and 9.71 mgg-1 for nickel(Cu>Sb>Ni>Mn) by Scenedesmus cells. According to AFM images,deformation was detected in two algae cell walls treated with heavy metals compared to untreated cells. For thisstudy, Freundlich adsorption model best fitted the data for all metal ions with 1/n value <1. As a result, whenthe results obtained in the study are revealed that Chlorella and Scenedesmus cells were an effective adsorbentfor removal of the four heavy metals, especially Cu2+ ions from aqueous solutions due to its high efficiency ofCu adsorption.
