Abstract
The rapid advancement in textile and printing trades has displayed damaging
effect to the marine environment as the manufacturing waste including toxic dyes
percolated into the surrounding. The presence of high amount of dye toxins in
aqueous media possesses harmful effect on the health of living beings. Therefore,
the main aim of the current chapter deals with the emerging potential of nanobased techniques for the effective removal of dyes from polluted water. The large
surface area, high chemical stability and superior catalytic activities made the
nanomaterials as potential candidate for the removal of dyes. The correlation
between the morphology and size of nanomaterials has also been discussed with
reference to their dye removal efficiency. The corresponding effect of dosage
amount, type of solvent, pH of the reaction media and presence of interfering ions
has also been discussed with reference to the dye removal efficiency in presence
of nanomaterials. The chapter has highlighted the detailed effect of nano-based
methodologies that had been used for the treatment of waste water having toxic
dyes as effluent. The current chapter has provided the in-depth review in the field
of sustainable way for waste water treatments.
