The Ni(II) removal capacity of magnetic nanoparticle loaded carbon derived from Morinda citrifolia (MMCSC) seed as compared to pure Morinda citrifolia seed powder (MCS)has been evaluated by varying different parameters such as contact time, pH and adsorbent dose during batch adsorption processes. Surface morphology, elemental analysis and functionality of the synthesized materials are characterized by SEM, EDX and FT-IR. The equilibrium data were found to fit well in the Langmuir isotherm. The monolayer adsorption capacity of CMC and MNCMC onto Ni(II) ions are found to be 45.50 and 266.67 mg g<sup>-1</sup>, respectively. The thermodynamic parameters indicated that the adsorption process is spontaneous and exothermic in nature. A single-stage batch adsorber is designed to estimate the amount of adsorbent required to treat the known volume of the effluent using the Langmuir adsorption isotherm. Regeneration study showed that MNCMC could be effectively utilized for the removal of Ni(II) ions for seven cycles of operation under study when compared with CMC.

Abstract


The Ni(II) removal capacity of magnetic nanoparticle loaded carbon derived from Morinda citrifolia (MMCSC) seed as compared to pure Morinda citrifolia seed powder (MCS)has been evaluated by varying different parameters such as contact time, pH and adsorbent dose during batch adsorption processes. Surface morphology, elemental analysis and functionality of the synthesized materials are characterized by SEM, EDX and FT-IR. The equilibrium data were found to fit well in the Langmuir isotherm. The monolayer adsorption capacity of CMC and MNCMC onto Ni(II) ions are found to be 45.50 and 266.67 mg g<sup>-1</sup>, respectively. The thermodynamic parameters indicated that the adsorption process is spontaneous and exothermic in nature. A single-stage batch adsorber is designed to estimate the amount of adsorbent required to treat the known volume of the effluent using the Langmuir adsorption isotherm. Regeneration study showed that MNCMC could be effectively utilized for the removal of Ni(II) ions for seven cycles of operation under study when compared with CMC.
