“…In recent years, other new applications have been suggested for the bagasse, one of them is wastewater treatment (13)(14)(15)(16)(17)(18). To date, removal of heavy metals, especially lead ions by means of bagasse, as a potentially effective adsorbent, has been developed (19)(20)(21).…”

Background: Nowadays, water pollution by toxic elements has become a universal environmental issue. Lead, as a toxic element, is approximately enhanced in the environment by industrial development. The potential risk of lead to health has attracted the interest of researchers to eliminate it from contaminated water. Objectives: In the present study, a dithizone-modified bagasse adsorbent, used for removing lead ions from aqueous solutions, was successfully prepared. Methods: The prepared adsorbent was characterized by FT-IR and XRD techniques. The adsorptive properties of adsorbent were studied at room temperature. Different parameters like pH value, solution concentration, adsorption time, and amount of adsorbent were optimized. Results: Results show that the adsorption of lead on dithizone-modified bagasse fitted well to the Freundlich isotherm equation following the Langmuir isotherm. The maximum removal efficiency was obtained to be more than 99.5% in a short contact time (1.0 minutes) at pH 6. The loading capacity was studied and obtained to be 37.20 mg g -1 . The adsorption process was replicated for 4 times without a considerable loss in its efficiency (> 95%). Conclusions: High efficiency at a short time, recyclability, and biodegradability are the main advantages of this adsorbent. The proposed method is cost-effective and environmentally friendly.

“…Blast furnace sludge has also been utilized for the removal of dyes and phenols by Jain et al [123] Bagasse, bagasse pith, bagasse fly ash. Raw bagasse is a waste from sugar mills and has been used as a low-cost adsorbent for elimination of chromium and nickel from aqueous solution by Rao et al, [124] who reported the effect of hydrogen ion concentration, contact time, sorbent dose, initial concentrations of adsorptive and adsorbent and particle size in batch experiments. The efficiency of the material for the removal of Cr (VI) at pH 6 and Ni (II) at pH 8, with a sorbate concentration 100 mg/L, contact time 90 min, adsorbent particle size 75 µm, and adsorbent dose 3.5g/L, was found to be 91 and 85.6%, respectively.…”

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.
