Description 95-104
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-1, 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.
