Heavy
metal contaminants are present in wastewater from many industries such as metal
manufacturing, dye and paint, chemicals and fertilizer. Heavy metal removal has
become the main priority for the environmental concern due to the toxic. Banana
peels are a low-cost agriculture waste which could be used for the adsorption
of heavy metals in wastewater. Hence, this study focused on the adsorption
capabilities of dried banana peels powder under various conditions such as the
effect of agitation speed, temperature and contact time for efficient
adsorption rate by using agricultural waste adsorbents which is banana peel
(treated by acid and alkali). Although banana is one of the most important
commercial crops in the world, most of the edible parts are consumed for its
nutrients purpose only rather than using adsorption properties. In that case,
the banana peels are used in adsorption of heavy metals where it extract out
the Cu and Pb from the waste water from the industries. The findings of this
study will contribute to bridging up the gap in knowledge on the potential of
using banana peels for promoting in the adsorption process and minimize the
effect on the living things caused by the waste water released by the heavy
industries.The results from the optimized method revealed the
applicability of the method to environmental water samples. This study
therefore confirms that banana peel is a promising adsorbent for the removal of
heavy metals from industrial effluent.
