ABSTRACT A novel nanoscale zerovalent iron-Sargassum swartzii (nZVI-SS) biocomposite was tested for its ability to remove malachite green from aqueous solutions. Batch equilibrium tests at different pH conditions showed that at pH 10, a maximum removal of 142.85 mg/g was observed according to Langmuir model. Involvement of various functional groups of the biosorbent in preferential biosorption of cationic dye was observed using Fourier transform infrared spectroscopy. Morphological changes occurring on the biocomposite materials were characterized using scanning electron microscopy. Furthermore, temperature and kinetic profiles during the biosorption process were also reported.
