Abstract:The cellulose matrix was characterized by FTIR, 13 C NMR, XRD, TG, SEM and applied in the removal of the reactive red RB dye in an aqueous medium, with a capacity of adsorption at a pH of 2.0, and an adsorption equilibrium time which was reached at around 200 mins. The kinetic study for the system followed the Elovich model. The adsorption isotherms for the system at temperatures of 35°C, 45°C, and 55°C were adjusted to the Langmuir, Freundlich, Sips, and Redlich-Peterson non-linear models, with a capacity of adsorption for adsorbent of 5.97 mg g , respectively. The adsorption occurred by electrostatic interactions and it was favorable and spontaneous, with the influence of temperature.

Nanomaterials have been extensively studied for heavy metal ions and dye removals from wastewater. This article reviews the role of nanomaterials as effective adsorbents for wastewater purification. In recent years, numerous novel nanomaterial adsorbents have been developed for enhancing the efficiency and adsorption capacities of removing contaminants from wastewater. The innovation, forthcoming development, and challenges of cost-effective and environmentally acceptable nanomaterials for water purification are discussed and reviewed in this article. This review concludes that nanomaterials have many unique morphological and structural properties that qualify them to be used as effective adsorbents to solve several environmental problems.

“…The analysis of electroplating effluent is revealed that it contained comparatively higher concentration of Cu (II) than ETP effluent. Other metals such as iron and nickel were also present (Machado et al, 2011). The organic load of both the effluent was very low (Machado et al, 2010(Machado et al, , 2011Javaid et al, 2011).…”

Environmental pollution affects the quality of atmosphere, lithosphere and biosphere. Efforts have been made in the last two decades to reduce the pollution sources and remedy the polluted water sources. Water quality monitoring in developing countries is inadequate especially in stream water affected by urban effluent and runoff. The purpose of this study was to investigate heavy metal contaminants in sank stream water in Gwalior. The water sample from stream and industrial effluents that drain into the stream were collected and analyzed for the total elemental concentration using atomic absorption spectrophotometer. The result showed that:-the wastewater was highly encircled with copper above the maximum permissible limit. 2) the level of dissolved oxygen was below the maximum permissible limit, while biological oxygen demand was above the maximum permissible limit. All industrial effluents/wastewater were classified as strong. Factors analysis results reveal two sources of pollutants; multiple origin of copper and mixed origin or chemical phenomena of industrial and vehicular emission.
