Removal of Cr (VI) from wastewater using activated neem bark in a fixed-bed column: interference of other ions and kinetic modelling studies
U Maheshwari, S Gupta - Desalination and Water Treatment, 2016 - Taylor & Francis
Continuous adsorption experiments are carried out in a fixed-bed to evaluate the
performance of a newly developed low-cost adsorbent (activated neem bark, ANB) for the
removal of Cr (VI) along with other metal ions (Cu & Zn) from aqueous solutions. The effect
of initial Cr (VI) concentration, mass of adsorbent and flow rate on the breakthrough curve
are studied. It is observed that as there is an increase in the initial concentration of Cr (VI)
from 50 to 100 mg L− 1, the mass of the adsorbent from 25 to 175 g, and flow rate from 5 to …
