Magnetic Nanomaterials for Dye Sensing and Removal

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Varied applications of nanomaterials have transformed various industries in the modern day. In recent years, magnetic nanoparticles (MNPs) have gained research interest from their applications in the environmental, agricultural, catalysis, medical and biosensing fields. This chapter explored the potential of MNPs in dye sensing and removal using pre-existent studies. Findings showed that MNPs are widely used in sensing various ionic and non-ionic dyes such as the azo, acid, cationic, reactive and dispersive dyes. The sensing and removal abilities were associated with the superparamagnetic, high surface area and adsorptive characteristics of MNPs. The characteristics can be improved and customized using controlled surface engineering to produce functionalized nanomaterials with high sensitivity to specific dyes. Optimizing the dye concentration, pH, temperature and adsorbent quantity can further optimize the dye sensing and removal capacities. The chapter aimed at assessing the potential of MNPs in dye sensing and removal for greener remediation of pollutants.
