Abstract
In textile industry, various dyes are used which are not completely attached to surface, a part
of dyes is directly discharged into surface water bodies and subsurface geological formations.
The change in physical, biological, or chemical water quality has detrimental effects on living
organisms thereby causing water borne diseases. It is estimated that the annual production of
dyes is 700 thousand tones, and the hundred thousand types of dyes are used throughout the
world. Many dyes are non-biodegradable, toxic and persistent in nature. It is very important to
remediate these dyes from contaminated water with cost effective techniques. Therefore, the
aim of this study is to evaluate the adsorption potential of Corn offals biomass (CO) and its
composites with zinc oxide (CO/ZnO), and magnetite nanoparticles (CO/MNPs) for the
removal of Cresol red dye (CR) from contaminated water. The effects of adsorbent dose (1 – 4
g/L), initial concentration (25 - 200 mg/L) of CR, pH (2 - 8), and contact time (0 - 180 min)
were evaluated. The adsorbent materials were characterized with FTIR, SEM, and EDX. The
CR removal was 70-57.2%, 72-61.4%, and 72.9-67.5% by using CO, CO/ZnO, and CO/MNPs
particles respectively, when the solution concentration was changed from 25-200 mg/L. It is
suggested that the low-cost adsorbent and its nanocomposites are efficient for the remediation
of dyes from contaminated water.

Keywords: water borne diseases; contaminated water; FTIR; SEM; EDX.
