REMOVAL OF TOXIC METALS FROM AQUEOUS ENVIRONMENT USING VARIOUS ADSORBENTS: A REVIEW
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 3
Abstract
In Recent decades, there has been an increasing public awareness of the long-term effect of water containing dissolved toxic metal ions. Toxic metals are known to be detrimental to plants, animals and humans. Even at very low concentration they adversely impair the nervous, digestive and skeletal system. Toxic metal contamination has been a crucial issue because these metals tend to persist and accumulate in the environment. Aquatic environment are particularly sensitive to toxic metal contamination possibly due to the structure of their food chain. This is because toxic pollutants are directly or indirectly introduced into aqueous environment significantly as a result of various industrial effluent injections in natural water bodies. In this review, presence of heavy metals in aqueous environment, its non bio-degradable properties, its high toxicity, followed by removal of these toxic metals using different techniques are discussed.
