Abstract
Direct disposal of industrial effluents into surface water bodies adversely affects the quality of
water. These effluents contain pharmaceutical compounds like Ibuprofen (IBP), which are very
toxic for humans and animals. Therefore, the present study aims to evaluate the batch scale
potential of Cotton Shells biosorbent (CSB), Cotton Shells biochar (CSBC) and its composites
with copper oxide nanoparticles (CSBC/CuONPs) and Magnesium oxide nanoparticles
(CSBC/MgONPs) to remove IBP from aqueous systems. In this study different process
parameters were evaluated such as impact of initial concentration (10-100 mg/L), impact of
dose (1-4 g/L), impact of pH (2-10), temperature (30- 50 0C) and time (0-180 minutes).
Kinetics and equilibrium models were used to simulate the experimental results. It was
observed that the removal of IBP was changed from 52.63- 32.98%, 61.40-47.02%, 74.56-
54.91%, and 87.72-70.70% by using CSB, CSBC, CSBC/MgO, and CSBC/CuO respectively,
when the initial concentration of IBP was changed from 10-100 mg/L and all other parameters
were kept constant. Moreover, the removal was increased significantly with increasing contact
time. In kinetics, Pseudo first order was most suited with 0.99 correlation coefficient while in
equilibrium, Freundlich model was suited. The order of removal was
CSBC/CuO>CSBC/MgO>CSBC>CSB. In this study it was noticed that the nano composited
are more promising than simple adsorbents and these can be used for broad scale removal of
IBP from contaminated water.
