“…A nanobiosorbent was fabricated via microwave crosslinking of nanosilica gel with banana peels nanobiochar (BPNB) and chitosan hydrogel (Chit Hgel) to produce BPNB-NSiO2-Chit Hgel nanobiosorbent (22.48-26.23 nm) [57]. The influence of nanobiosorbent dosage (1-50 mg), pH (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12), reaction time (1-45 min), dye concentration (5-100 mg/L), temperature (15-60 o C), and interfering salts on the adsorption of Congo Red was investigated. Maximum dye uptake were about 58 mg/g.…”

The presence of organic dyes in aqueous environments is of extreme hazardousness against life due to the toxicity of these compounds. Thus, its removal from these various aquatic media is of the utmost importance and several technologies are constantly proven to match this goal. Among these technologies, various types of degradation and adsorption are the most widely used, and of the various types of materials used within these technologies, nanomaterials are constantly developed and investigated, probably due to the various properties that these nanomaterials presented. This work reviewed recent developments (2023 year) about the use of these nanomaterials on the treatment of solutions contaminated with these toxic organic dyes.

The present research evaluated the potential use of the macroalgae biomass Sargassum sp., which was modified with a filamentous fungus Cunninghamella echinulata for the biosorption of methylene blue (MB) dye. The modified fungal biomass (FERsarg) was obtained through solid-state fermentation. The FERsarg showed a pHPZC of 7.9, a low mass loss, material micro/mesoporous, and the presence of hydroxyl, carboxylic, phenolic, and carbonyl functional groups. The influence of dosage, solution pH, contact time, initial concentration, and temperature were evaluated for MB biosorption, and the best results were obtained at 2 g L-1 and pH 6. The kinetic study revealed a better fit for the pseudo-second-order model, while the Sips model best described the equilibrium experimental data. The equilibrium was attained within 180 min and showed qmax yielding of 115.49 mg g-1 at 323 K. The thermodynamic understanding of the present research revealed that the biosorbent exhibited spontaneous, exothermic, and physical nature of MB removal. The adsorptive mechanism shows that the process was controlled by electrostatic attraction. The present results reveal the viability of using fermented biomass as a potential adsorbent, contributing to the follow-up of zero waste, and support the concept of circular bioeconomy.
