In the present study, chitosan functionalized magnetite nanoparticles (CS@MNPs) were synthesizedby a simple and economical coprecipitation technique for efficient magnetic removal of allura red dye(ARD) by adsorption technique from the aqueous solution. Size and surface properties of the bare andsurface functionalized MNPs were determined with the help of XRD and TEM technique. Surfacefunctionalization of the bare MNPs was confirmed with the help of FT-IR spectroscopy and TGAtechniques. Magnetic properties of the synthesized bare and functionalized MNPs were determinedby VSM technique. The effect of various parameters including adsorbent dosages, contact time,temperature on adsorption capacity of the CS@MNPs for allura red dye were investigated with thehelp of UV-vis spectrophotometer. The pseudo second order kinetics and Langmuir adsorption isothermmodel were found to fitted well with the adsorption process of dye onto the chitosan functionalizedmagnetite nanoparticles (CS@MNPs).
