“…There have been several developed adsorbent materials for the removal of dyes from water and wastewater, with activated carbon regarded as the best of all and highly preferred (Martins and Nunes, 2015). However, the high cost of procurement, sludge production and regeneration problem have been the most significant constraints in the use of activated carbon as pollutant removal, including dyes.…”

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.

“…For activated carbon, the adsorptive properties are determined not only by its porous structure but also by its chemical composition, and oxygen surface groups are formed by reaction with oxygen during the carbon preparation steps. The nature of these oxygen surface groups-carboxyl, carbonyl, phenol, ether, and lactone-is responsible for the basic or acid character of the carbon, which is a key parameter for an efficient adsorption between the adsorbent and the adsorbate (Martins and Nunes, 2015). Biosorption process by agricultural by-product is a friendly approach and has been proved to be a cost-effective and nonhazardous technology for the removal of heavy metals from water (Tajernia et al, 2014).…”

Fe(II) contaminant in groundwater is one of the most important in the environmental pollutions as it affects the taste, esthetic quality of the water and turns the color of the water to red-brown. Moreover, when Fe(II) contaminate in large amounts, it is harmful to health. The objective of this study was to evaluate the performance of Fe(II) removal in aqueous solution by the low-cost adsorbents namely, sugarcane bagasse (SB) and activated carbon prepared from sugarcane bagasse (ACSB). The two adsorbents were characterized by BET, FTIR, SEM, and XRF. The adsorption behavior of SB and ACSB for Fe(II) in aqueous solution was investigated as the function of pH (1-5), contact time (5-360 min), initial Fe(II) concentration (50-250 mg/L), and temperature (20-40 o C). The adsorption data were analyzed by isotherm and kinetic models. The experimental equilibrium data were best fitted with the Langmuir isotherm model and the maximum monolayer adsorption capacity values were 39.52 and 131.57 mg/g for the SB and the ACSB respectively. The kinetic adsorption data were found to fit well with the pseudo-second-order kinetic and intraparticle diffusion models. Thermodynamic analysis results showed that the adsorption of Fe(II) was spontaneous and endothermic in nature, and was controlled by physical mechanism. In summary, the findings suggested that SB and ACSB were efficient adsorbents, and ACSB showed higher removal of Fe(II) from aqueous solution.

The main problem of the textile industries are releasing the massive amount of dyes in river or other water system. Owing to this badly behaviour results in contamination of underground water and damaging the entire ecological system. The main challenge is treatment of the polluted water without damage of environment. Over the past years, numerous techniques for the treatment of textile wastewater including of membrane filtration [1], ozonation [2], biosorption [3], electro coagulation [4], photo catalytic removal [5], coagulation and flocculation [6], electrochemical precipitation [7]. Nevertheless, these methods having some inadequacy to remove the dyes from wastewater. Nowadays, adsorption technique is a well-known method for the treatment of wastewater from dyes and heavy metals. At present, adsorption techniques have been considered owing to the low cost, ease of operation and less amount of residue. The dyes can be efficiently removed by adsorption technique in, which the liquefied dyes attached themselves to the adsorbent surface. Several adsorbents have been used for removal of dyes from aqueous solution. The adsorbents such as recycled alum sludge [8], waste coir pith [9], fir wood [10], rotton saw dust [11], fly ash [12], coconut shells [13], activatedWe report in present work the simple procedure to synthesize ball clay-manganese dioxide (MnO2) nanocomposites. The as-synthesized nanocomposites were characterized using powder XRD, FT-IR, SEM, TEM and BET surface area, respectively. Recently the explorations of clay modification for developing the adsorbent ability to get rid of the toxins from water. The XRD result indicates that the nanocomposite was crystalline in nature. The FTIR spectra showed that the native ball clay was successfully converted to ball clay-MnO2 nanocomposites, which were identified by the change in peaks. The SEM images of the ball clay-MnO2 nanocomposites showed that development in surface area. The TEM images indicated that the size of the nanoparticle. The BET studies of as synthesized ball clay-MnO2 nanocomposites indicate that surface area, total pore volume and average pore diameter values.This is an open access journal, and articles are distributed under the terms of the Creative Commons Attribution-NonCommercial 4.0 International (CC BY-NC 4.0) License, which allows others to copy and redistribute the material in any medium or format, remix, transform, and build upon the material, as long as appropriate credit is given and the new creations are licensed under the identical terms.
