Abstract :
Textile industries produce lot of undesirable
biological or chemical substance, that are contaminated.
These contaminates are in form of acidic or caustic
dissolved solids, toxic compound, and different dyes.
Some organic dyes are hazardous and have adverse
effect on living organisms (Mohammed, 2014). Large
percentage of the dye does not bind to the fabric during
coloration, thus it is easily loss in wastewater stream.
During dyeing process, some percentage of dyes are
released into the environment, thus colourising the
effluent highly colored and making it aesthetically
unpleasant in different industrial applications and
aquatic ecosystems (Ahmad et al., 2015; Aksu, 2005;
Brillas, and Martínez-Huitle, 2015). Dyes are resistance
to light, microbial attack, recalcitrant and toxic to water
temperature, ejecting them into water bodies usually
inhibit penetrations of sun lights essential for
photochemical and biological activities by the aquatic life
(Ertugay and Acar, 2017; Mittal et al., 2014). Therefore,
adequate treatment of industrial wastewater containing
dyes prior to discharge is advantageous, by effectively
extractingdye color in order to protect the environment.
Methylene blue was used as adsorbate and
conventionally activated hamburger seed shell as
adsorbent. The experiment was done using a simulation
method due to inability to solely separate all other
elements present in textile waste water. The Kinetics of
the adsorption was matched into 4 Kinetic models the
first order kinetic1 model, second order kinetic2 model,
pseudo first and second order kinetics3,4 model
respectively, it was then observed that the adsorption
kinetic matched best to the psuedo second order kinetic4
model, which had high coefficient of correlation between
the calculated and experimental adsorptive capacities.
Langmuir and Freundlich isotherm models was used to
analyse the data. Isotherm data matched the Freundlich
model. Contact time, pH. dye concentration and
absorption dosage were studied. The data were analyzed
by calculating the adsorptive capacity and percentage
removal at equilibrium. The result shows that contact
time while the effect of initial concentration increases
with decrease in percentageremoval, while the percentage
removal increases with increase in adsorbent dosage,pH.
The percentage removal of methylene blue increased
with decrease in initial methylene blue concentration and
increased with increase in contact time and dose of the
adsorbent. This research is vital to management of
agricultural waste, and its industrial application. It will
empower researchers to focus on agricultural waste
rather than disposing randomly. It is beneficial for
environment protection, to carry out proper treatment
of industrial wastewater containing dyes prior to
dischargeby effectively extracting dye color.
