“…The samples were mounted on the copper stub using an adhesive carbon tape. Then the samples were sputtered with platinum for 120 seconds at 30 mA under high vacuum until they were completely covered and ready to be used for the microscopic analysis [9]. The FE-SEM micrograph were observed using JEOL JSM-7600F Field Emission Scanning Electron Microscope (USA).…”

“…Then the peels were soaked in distilled water for further clean up at least for 24 hours followed by oven drying at 60°C for 24 hours to substantially remove its moisture content. The dried peels were then ground to fine powder using domestic blender and sieved to obtain desirable particle size of < 150μm [9,10]. Final products were kept in air tight plastic container for further analysis.…”

Abstract. This study investigates the chemical and morphological characteristics of cassava peel (CP) biomass as a potential coagulant aid for turbidity, heavy metals and microbial removal. FE-SEM micrograph shown the surface of the CP samples was covered with smooth and globular in shaped of bound starch granules. FTIR spectra demonstrated that carboxyl and hydroxyl groups were present in abundance. Whereas analysis by XRF spectrometry indicated the CP samples contain Fe 2 O 3 and Al 2 O 3 which might contribute to its coagulation ability. The features of CP obtained from this study promotes the feasibility of CP to be further developed and studied to produce effective coagulant aid as sustainable alternative to reduce the usage of chemical coagulants.

Remoción de azul de metileno de soluciones acuosas utilizando cáscara de yuca (Manihot esculenta) modificada con ácido fosfóricoRemoción de azul de metileno de soluciones acuosas utilizando cáscara de yuca (Manihot esculenta) modificada con ácido fosfórico RESUMENEste trabajo reporta la modificación de la cáscara de la yuca con ácido fosfórico para la remoción de azul de metileno de soluciones acuosas. Se utilizó una metodología experimental con diseño compuesto central 3^2+estrella, variando la temperatura de modificación de la cáscara de yuca (113°C a 127°C), la relación biomasa-ácido fosfórico (1:0.5 a 1:1.5) y la concentración inicial del colorante (100 a 800 mg/L), utilizando como variables de respuesta el porcentaje de remoción y la capacidad de adsorción. Se encontró que, para el porcentaje de remoción del colorante, la variable más importante es la temperatura y que la capacidad de adsorción se favorece a concentraciones altas de colorante. La cáscara de yuca modificada a la temperatura más alta (127°C) y relación másica de biomasa-ácido 1:1 presentó mayores valores tanto para el porcentaje de remoción como para la capacidad de adsorción, los cuales fueron de 99.984% y 79.975 mg/g, respectivamente. La cinética de adsorción se ajustó al modelo de pseudo segundo orden lo cual sugiere que el proceso se realiza por quimisorción, además, ajustó con las isotermas de Freundlich, lo que sugiere que la adsorción se realiza en múltiples capas.Palabras clave: Cáscara de yuca; Azul de metileno; Remoción; Adsorción; Cinética; Isotermas de equilibrio. ABSTRACTThis work reports the modification of cassava peel using phosphoric acid for the removal of methylene blue from aqueous solutions. A central composite design 3^2+star was employed using as manipulated variables the temperature of modification (113 ° C to 127 ° C), the biomass-phosphoric acid ratio (1: 0.5 to 1: 1,5) and the initial concentration of dye (100 to 800 mg/L); the response variables of the experiment were the percentage of removal and the adsorption capacity. It was found that for the percentage of removal of dye, the most important variable is the temperature, and that the adsorption capacity is favored at high concentrations of dye. The cassava peel modified at the highest temperature (127 ° C) and biomass:acid mass ratio 1:1 showed higher values for both the removal percentage and the adsorption capacity, which were 99.984% and 79.975 mg/g, respectively. The adsorption kinetics was best adjusted to a pseudo second order kinetic model, which indicates that the process is carried out by chemisorption, also, the process was adjusted to Freundlich isotherms, indicating that the adsorption is carried out in multiple layers.

“…The maximum adsorption of78.62% was acquired for inlet concentration of 50 mg/L, carbon bed height of 30 cm and flow rateof 13.3 mL/min. The ability of cassava husk to eliminate Cu(II) from aqueous solution was also evaluated and a maximum absorption ability of 41.77 mg/g was reported [72]. The feasibility of cassava husk waste for Ni sorption was also evaluated [73].…”

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.
