Role of Carbon Materials in the Removal of Organic Pollutants: An Abridged Review

Abstract

The unraveling of ill-effects of organic pollutants like pesticides and dyes has been showcased with various devastating incidents worldwide, which seriously affect aquatic biota. Even still, it can around 180000 fatalities per year noted in developing countries due to pesticide poisoning. Besides concomitant organic pollutants, organic dyes like azo dyes are highly persistent, non-biodegradable, and carcinogenic. On peeping into perils of pesticides and dyes, a birds-eye focused on different methods for their wiped out from water bodies. In recent times, the adsorbents like carbon nanotubes and graphene were being used in the adsorption method for their elimination. Additionally, graphene properties include a ratio of rich surface area and volume, honeycomb structure rich in aromatic appearing like a large polyaromatic molecule, and good chemical stability induced metamorphosis into adept nano adsorbents. Furthermore, the methods of adsorption, kinetics, and mechanism are also reported in this review to elicits the extent of adsorption. However, the purview of this present review was about graphene materials and their impact in removing dyes and pesticides through the adsorption method.
