“…Compared to other carbon-based materials, GO have better environmental compatibility and biocompatibility. Oxygen-containing functional groups can be used as the adsorption sites [27]. Through interaction with these oxygen-containing functional groups, dyes can be easily electrocoagulated.…”

This work has been carried out to minimize environmental pollution by investigation of efficient electrocoagulation of methylene blue by aluminum electrode cell setup using graphene oxide as adsorbent. The efficiency of dye removal was evaluated by the absorbance of methylene blue at 665 nm. The operating parameters for electrocoagulation such as current density (10-30 mA/cm 2), electrolysis time (5-20 minutes), pH of the medium (2 to 10), stirring speed (150-350 rpm), inter electrode distance (0.8 to 2 cm) and NaCl concentration (1.5-5.0 g/L) were optimized and found to be 30 mA/cm 2 , 20 min, pH 7.0, 300 rpm, 2 cm and 5 g/L respectively. The results showed that the dye removal efficiency was enhanced to 99% by the addition of graphene oxide. The result of the present research work can be useful for an efficient large-scale treatment of industrial effluents contaminated with methylene blue.

“…8 Many kinds of absorbents are commercially available for specic pollutant removal applications. 5,13,14 For example, activated carbon (AC) is frequently applied to remove heavy metals and other pollutants owing to its high surface area and mesoand micro-porosity. Nevertheless, AC is conventionally prepared from non-renewable coal, which raises the cost and results in difficulty during disposal and regeneration.…”

“…The industrial activities, especially textile processing is one of the high water-intensives which aided pollution of water bodies with high concentrations of dyes, total dissolved solids, chemical oxygen demand, biochemical oxygen demand, heavy metals, surfactants and many other toxic organic compounds and also contributes to the depletion of available water resources (Vergili et al, 2012;Tehrani-Bagha et al, 2010;Salleh et al, 2011). Among these organic pollutants, dyes are found to be the most common, recalcitrant, challenging to biodegrade and noxious pollutants (Peng et al, 2016;Ali et al, 2019).…”

Dyes, especially from textile industries, are significant pollutants in water and wastewater, which have become pervasive in the environs to which they are discharged. The effluents containing different types of dyes have become ubiquitous in the environment. While several treatment techniques have been developed to address the removal of recalcitrant dyes from water and wastewater, the adsorption technique is highly preferred due to its many advantages. However, selecting the appropriate alternative adsorbents with high adsorption capacity to costly activated carbon has continued to receive great attention. This book chapter reviewed the applicability of adsorptive techniques of agro-waste based adsorbents for the removal of dye pollutants from water and wastewater. The mechanisms of persistent dye pollutant removals based on the adsorption processes were adequately described. Further, the strengths, weaknesses, opportunities and threats (SWOT) of using agro-waste materials as alternative adsorbents are also accounted.
