Abstract

Water scarcity along with a decrease in the quality of water due to various pollutants is adding to the already existing problems related to water. Due to urbanization and industrialization, there has been an increase in the level of heavy metals present in water resources which is decreasing the quality of water and causing serious health issues, and therefore heavy metal levels need to be monitored, and their concentrations must be reduced in water resources using different techniques.

Tree barks are known widely for their availability as well as low-cost metal chelating property for the adsorption of metals in an aqueous environment which acts as a biosorbent.

It is known that the barks have a clarifying property and certain heavy metal uptake values analyzed and attained reduction using different species of tree barks. The numbers obtained are compared with the activated carbon sources which were commercially available. Bark being easily available and low cost over activated carbon has the possibility to be used without any pretreatment. Selection of specific bark species are usually suggested due to their specific activity with the heavy metals. Natural adsorbents are gaining importance due to their low cost and eco-friendly nature compared to other chemicals, where in the removal of heavy metals by certain tree bark species is a new technique in itself.
