Author Description

Heavy metals are found abundant in the water sources due to the rapid industrial and agricultural development together with the population growth. Metals from polluted water bodies can then enter into the surrounding soil, surface water, and groundwater. Polluted water when consumed by living organisms, the toxic heavy metals can accumulate and cause harm. It is important to remove heavy metals from industrial sources before they enter into the environment. Conventional treatment processes for removal of heavy metals are either very expensive, generation of large volume of chemical sludge and extra operational cost are required for sludge disposal. The book is about to develop a low cost sorbent for effective removal of heavy metals from Industrial waste water and to determine removal efficiency of biosorbents (pine wood, paper mulberry wood/bark and rice husk bio-chars) in comparison with commercially available (silica powder) under different experimental conditions. Method of preparation of biochars and heavy metals removal efficiency of biochars has been described in detail.
