The Ability of Composite Ni/Al-carbon based Material Toward Readsorption of Iron(II) in Aqueous Solution

In this research, NiAl-LDH was synthesized using the coprecipitation method and modified with biochar graphite to produce NiAl-biochar NiAl-graphite composite materials. The adsorbent that has been is used for application of adsorption Fe(II) ions in aqueous solution. resulting material characterized by XRD (X-ray Diffraction) analysis, spectrophotometer FT-IR, BET analysis determine specific surface area TG-DTA analysis. diffractogram showed NiAl-Biochar had diffraction pattern characteristic precursor. LDH will have a larger than reaches 438.942 m2/g NiAl-graphitereaches 21.595 m2/g. This supports adsorbents large capacity adsorb metals. Adsorption Fe (II) stable five regeneration cycles (<75.30%). ion process tends follow Langmuir isotherm model which maximum value (Qmax) reaching 20 times 243.902 mg/g 72.464 mg/g, so carbon-based considered effective. remove can increase stability structure regeneration. results thermodynamic parameters endothermic, tookplace spontaneously solid-liquid phase interface increased according increasing degree disorder.
