Abstract—This study investigates the applicability of
maghemite nanoparticles (MNPs) for the removal of total
chromium (TCr) from the tannery wastewater (TWW). The
MNPs of 122 nm were synthesized using a co-precipitation
method and characterized by Nanometer particle size analysis
(NANOPHOX), transmission electron microscopy (TEM) and
X-ray diffraction (XRD). Batch experiments were carried out
for the removal of TCr from the TWW by MNPs. The effects of
dosage of MNPs, pH, initial concentration and contact time on
TCr removal were investigated. Maximum removal efficiency
of TCr in the TWW was achieved 96.7% at optimum condition
(pH 2, MNPs dose was 0,5g/L, initial concentration of TCr was
33,2 mg/L, 40minute) at room temperature. It is observed that
the best efficiency in removing major physico-chemical
parameters (TCr, SS, COD, sulfide and turbidity) in the TWW,
which are well below the standard prescribed limits for МNS
6561: 2015.Thus the study suggests that the treatment with
MNPs could be promising to reduce pollutants from the other
TWW.
