ABSTRACT: Dyes are widely used
for colouring in
textile industries, significant
losses occur during the
manufacture and processing
of the product,
and these lost
chemical are discharged in
surrounding effluent. Adsorption
of dyes is
an effective technology
for treatment of wastewater contaminated by the mismanaged of different
types of dyes. In this research, we investigated
the potential of
rice husk ash
for removal of
methylene blue dyeing agent
in aqueous system.
The aim of
this research is
to find out
the optimum contact time
and pH on
the adsorption of
methylene blue using
rice husk ash.
Batch kinetics studies were carried out under varying experimental
condition of contact time and pH. An adsorption equilibrium condition was
reached within 10 minutes and the optimum condition for
adsorption was at pH 3.
The adsorption of
methylene blue was
decreasing with decreasing the solution pH value.
Keywords: methylene blue,
adsorption, contact time, pH
