“…CTS-MMT with a mass ratio of 0.25 showed the highest adsorption amount (150 mg/g) at 12 hr. The adsorption potential of CTS-MMT for cobalt in this study was compared with that of other reported adsorbents as summarized in Table 1 ( Manohar et al, 2006;Yavuz et al, 2003;Parab et al, 2006;Anoop Krishnan and Anirudhan, 2008;Ahmadpour et al, 2009;Suhasini et al, 1999;Erdem et al, 2004;Smiciklas et al, 2006;Repo et al, 2009;Bhatnagar et al, 2010). It can be seen that the prepared adsorbent in this study shows good performance for cobalt removal, which might be related to the combination of the advantages of both CTS and MMT.…”

“…The effect of different important parameters, namely, pH, dose of adsorbent, contact time, mixing speed, and initial oil concentration, and their ideal stipulations for maximum sorption efficiency were examined and results indicated that adsorbent dosage of 5g/L, contact time of 70 min, mixing rate of 45-50revolutions/min, and pH of 2 provided maximum oil elimination efficiency in this study. The feasibility of lemon husk waste was examined for the elimination of cobalt ions from aqueous solutions [56]. The maximum absorption ability of lemon husk adsorbent for cobalt elimination was ca.…”

Towards the future of green, sustainable and renewable products the suggestion of using the agriculture biomass in the coming decades got increased. Biomass material is one of the important sources of alternative material for the production of biocomposite products. An increasing global awareness about environmental issues is acting as the driving force behind the utilization of biomass material as valuable products. Bio-waste materials (agricultural waste) have been recognized as an ecological burden for the society they stimulated new gateways for the production of renewable, low cost and sustainable adsorbents for water treatment applications. In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and bacteria. Adsorption has proved that it is the best process of water treatment technologies, because of its significant advantages. Different modification methods of waste-based adsorbents, have also been presented to highlight and discuss the key advancements on the preparation of novel adsorbents using agricultural "agro-waste". Adsorption mechanisms responsible for pollutants removal by waste-based adsorbents have also been discussed. It also focuses on the computational aspects of binding of biomolecules to nanoparticles (NPs) and some of the applications of the biosynthesized NPs as water purification. The nature acts like a large ''bio-laboratory" comprising of plants, algae, fungi, yeast, etc. which are composed of biomolecules. These naturally occurring biomolecules have been identified to play an active role in the formation of nanoparticles with distinct shapes and sizes thereby acting as a driving force for the designing of greener, safe and environmentally benign protocols for the synthesis of NPs. The biosynthesis of NPs using waste materials will help researchers not only to design safer nanomaterials but also to promote the understanding of health and safety considerations of NPs. Useful materials can be produced easily even at reasonable scale because the biomaterial based routes eliminate the need to use toxic chemicals. The aim of this review is to summarize the adsorption capacities for organic and inorganic pollutants by different bio-waste-based adsorbents.

“…Environmental Bureau of Investigation (Canadian Water Quality Guidelines) has set the allowable limits of cobalt in the irrigation water and livestock wastewater at 0.05 and 1 mg L -1 , respectively (Rengaraj and Moon 2002). Bhatnagar et al 2010 carried out the sorption experiments with lemon peel at pH 6 and an incubation period of 10 h at 25°C and observed that lemon peel (adsorbent dose 10 g L -1 ) adsorbed 22 mg g -1 of cobalt from an initial concentration of cobalt up to 1,000 ppm. But the phenomenon was found to be temperature-dependent leading to less adsorption at temperature higher than 25°C.…”
