The objective of this research is focus on pollutants evaluation and remediation
of Tannery effluent discharged from Nigerian Institute of Leather and Science Technology
(NILEST) Zaria, Nigeria using activated Carbons as adsorbents. The received, spent and
Reborn Adsorbents (RGAC) were characterized using both classical (bulk density, ash content
and iodine number) and instrumental (AAS, SEM, FTIR and UV-Vis Spectrophotometer)
techniques. The role of different operating parameters on Cr uptake was investigated
from a batch adsorption mode. Data generated where fitted into four isotherm models viz;
Langmuir, Freundlich, Temkin and Dubinin-Radushkevich. The earlier estimated chromium
level in the tannery effluent which was above WHO and NESREA permissible limits was
considerably reduced via adsorption. On the general, results show good significance in the
adsorption behavior of the regenerated adsorbent compared to the commercial sample.
