In this study, magnetic nanoparticles (MNPSD) from abundantly available lignocellulosic waste viz. sawdust wassuccessfully synthesized via co-precipitation methodand consequently used for the removal ofmodel phenolics (Catechol and Resorcinol) from aqueous solution under batch mode method. Batch adsorption studies revealed irrespective of adsorbate types, higher sorption of such phenolics occurring at acidic pH (pH=3), contact time of 60mins and at 25ºC. The results obtained from pH studies indicatesthat electrostatic interaction may be responsible for the binding of Catechol and Resorcinol onto MNPSD, while film or particlediffusion mechanismsto be operative during the transfer of such phenolics from the liquidphase. The isotherm outcomes demonstratedthat irrespective of adsorbate types, Langmuir modelwas operative over the studied phenolics concentration and kinetics data followed pseudo-second-order modelover the entire time frame. Thus, the experimental results reveal the usefulnessof MNPSD as a suitableNano adsorbent for wastewater treatment.
