Adsorption of Cadmium (II) Ions from Aqueous Solution onto Mango Leaves
Journal Title: Asian Journal of Physical and Chemical Sciences - Year 2017, Vol 2, Issue 3
Abstract
The objective of this study was to evaluate the use of mango leaves for their ability to remove Cd2+ ions from aqueous solution by batch experiments. The adsorption of Cd2+ ions onto mango leaves were characterized by using various analytical techniques: Fourier transform infrared spectroscopy and Scanning electron microscopy. The effects of various parameters, such as solution pH, adsorbent dosage, initial concentration of cadmium ions, temperature and presence of chelating agent EDTA suppressed the uptake of Cd2+ ions were examined. The mango leaves investigated in this study showed good potential for the removal of cadmium from real industrial wastewater. The desorption test revealed that HCl was the best for the elution of metals from the tested mango leaves. The equilibrium data were well fitted with the Langmuir isotherms. In conclusion, the mango leaves was the favourable alternative of cadmium removal from water.
