Abstract
In raising substantial concerns, micropollutants occur in water resources worldwide
due to many causes. As a result, this has adverse impact on ecosystem especially
aquatic life and in turn on humans. Ion exchange method is the best method as polymeric
resin which has effective alternative adsorbent. This adsorbent has high porosity
and accessibility, significant adsorption sites and stable chemical properties.
Unmodified cellulose incorporated with the methacrylic acid to make it modified
cellulose increases efficiency for the adsorption of heavy metal ions.
In turn, modified methacrylic acid (CMAA) resin has good adsorption capability specially
for environmentally toxic metal ions: lead(Pb2+), copper(Cu2+), chromium(Cr3+) and
cadmium(Cd2+). Prepared resin showed higher retention of heavy metal ions by batch
and column method respectively. Sorption equilibrium is found when there is effect
of temperature on capacity of a cation exchanger. This study contains the preparation
or adsorption of methacrylic acid on cellulose to treat the industrial effluent.
Characterization of adsorbent was performed by FTIR and thermogravimetric analysis.
Experiments were performed at different pH, concentration of metal ion, contact
time etc.
