Utilization of Biomass Waste at Water Treatment
Cansado, I.P.P.; Geraldo, F.; Mourão, P.A.M.; Castanheiro, J.E.F.; Carreiro, E.P.; Suhas, SuhasThis work presents some preliminary results on the direct use of untreated biomass from agricultural activities as adsorbents for water treatment. Waste was also used to produce activated carbons (ACs) by chemical activation with KOH. The efficacy of agricultural waste such as stubble, sawdust from Teak (Tectona Grandis), fibers from Imbondeiro (Adansonia digitata L.), bamboo flowers, and other regional plants ...
An ingenious investigation on the adsorptive and antibacterial properties of a ...
Suhas, Suhas; Chaudhary, M.; Chaudhary, S.; Sing, M.; Dehghani, M.H.; Tyagi, I.; Cansado, I.P.P.; Kumar, S.; Kumar, S.A novel silver-doped hydrochar (Ag-HC-230) was synthesized at 230 °C via hydrothermal carbonization of Tectona grandis seeds (TGs). The characteristic properties of the Ag-HC-230 were investigated using FTIR, XRD, TGA, SEM and surface area measurements. These results were further utilized for exploring the removal efficiency of the prepared material for chemical and biological contaminants. The surface area and...
Effect of Substituent Groups on the Adsorption Efficiency of Phenols by Activat...
Suhas, Suhas; Kushwaha, S.; Chaudhary, M.; Chaudhary, S.; Tyagi, V.; Cansado, I.P.P.; Dehghani, M.H.In this study, the novel activated carbon developed from Phyllanthus emblica fruit stone, through hydrothermal treatment at low pressure and temperature, was utilized for the removal of 4-nitrophenol, 4-chlorophenol, and phenol from water. The activated carbon produced (AC-HTPEFS) showed a well-developed porosity with a surface area of 569 m2 g−1 and a total pore volume of 0.342 cm3 g−1. The adsorption process ...
A Review of the Biomass Valorization Hierarchy
Pestana da Paixão Cansado, Isabel; Geraldo, P.F.; Mourão, P.A.M.; Castanheiro, J.E.F.; Suhas, Suhas; Roman Suero, Silvia; Ledesma Cano, BeatrizThe sustainability of the planet is based on reducing the use of fossil fuels and greenhouse gas emissions. The recovery of biomass waste puts economically valuable materials into circulation, which can successfully replace fossil fuels and which would otherwise be sent to landfills. Based on the review of several published works, we observe that the referenced processes to value biomass or biomass waste are no...
Phenol removal onto novel activated carbons made from lignocellulosic precursor...
Valente Nabais, Joao; Gomes, Jose; Suhas, Suhas; Carrott, Peter; Laginhas, Carlos; Roman, SilviaThe adsorption of phenol from dilute aqueous solutions onto new activated carbons (AC) was studied. The novel activated carbon was produced from lignocellulosic (LC) precursors of rapeseed and kenaf. Samples oxidised with nitric acid in liquid phasewere also studied. The results have shown the significant potential of rapeseed and kenaf for the activated carbon production. The activated carbons produced by carb...

Valente Nabais, Joao; Laginhas, Carlos; Carrott, Manuela; Carrott, Peter; Gomes, Jose; Suhas, Suhas; Ramires, Ana; Roman, SilviaThe adsorption of phenol and mercury from dilute aqueous solutions onto new activated carbons was studied. These included activated carbons produced from novel precursors, namely rapeseed, vine shoots and kenaf, and samples oxidised with nitric acid in liquid phase. The results have shown the significant potential of rapeseed, vine shoots and kenaf for the activated carbon production. The activated carbons prod...
