“…The increase in population coupled with increasing technology led to increase in industrial growth and generation of heavy metals in industries, such as smelting, electroplating, lead-batteries cycling, metallurgy and many more (Igbinosa & Okoh, 2009;Shah et al, 2009;Vohra, 2010). As a result of these, stricter discharge regulations that could lowered permissible contaminant levels in waste streams had been enacted because of decrease in potable water, water resources and huge cost of treatment of waste water (Gupta et al, 2000;ESCWA, 2003).…”

Adsorption process had been effective in condensing and concentrating metal ions from aqueous phase to the surface of adsorbent, it is a well established technology that employed the use of synthetic adsorbent which are usually scarce and expensive in waste water treatment. Hence, there is a need to develop new adsorbent which are readily available at low cost to remove metal contaminants in aqueous system. In this work, raw sugarcane waste and raw okra waste which are agricultural by-products were used as adsorbent in the adsorption of Fe(III) Cd (II), Pb (II), Zn (II), Ni (II) from various aqueous solutions. Infrared spectrum of the okra and sugar cane waste were recorded to detect the functional groups that has the binding capability for the metal ion adsorption. Batch studies were performed to evaluate the adsorption process and its was found that the okra waste was able to adsorb 5.05% of Fe(III),), 44.95% of Cd (II),), 65.10% of Pb (II), 38.78% of Zn (II), 57.80% of Ni(II), while the sugarcane waste was able to adsorb 3.61% of Fe (III), 35.06% of Cd (II), 43.50% of Pb (II),), 24.45% of Zn (II), 35.31% of Ni(II). This work proved that raw okra waste was more effective adsorbent material than raw sugarcane waste for the removal of heavy metals from aqueous systems. The Freundlich adsorption model described well the sorption equilibrium of the metal ions however research study have shown that modified form of okra waste was an excellent adsorbent, there is possibility of modifying the raw sugar cane waste for better performance since it has potential of removing heavy metals in waste water.

Two-color infrared multiple photon dissociation (2c-IR-MPD) spectroscopy with delayed pulses indicates a torsional isomerization in a "ligand-metal-chelate" complex [AgL1L2](+). Ab initio calculations reveal the torsional barrier as well as the change in vibrational frequencies and IR intensities along the isomerization pathway. The current approach bears prospects for further elucidation of competing interactions within naked or microsolvated complexes in gas phase coordination chemistry.
