“…As análises de Espectroscopia Raman estão dispostas na Figura 4 para as amostras NM, MA, NM-Cr e MA-Cr. A lignina é frequentemente identificada com sua banda Raman característica em torno de 1600 cm -1 [33]. Como pode ser visto na Figura 4 a intensidade da banda nessa região é superior para a amostra NM, já para MA a intensidade da banda diminui muito, justificando a deslignificação sofrida pela MA quando tratada com o NaOH.…”

Dois biossorventes de Cr(VI), um não modificado e o outro com modificação alcalina, produzidos a partir da biomassa da vagem de Libidibia ferrea (LF) foram estudados pela presente pesquisa. Os biossorventes preparados foram caracterizados antes e depois da adsorção ao Cr(VI) através de diferentes técnicas, incluindo FTIR, MEV, EDX, análise de área superficial, volume e diâmetro de poros, e espectroscopia Raman. Além disso, estudos do equilíbrio e da cinética de adsorção também ajudaram a entender o processo adsortivo. Por fim, foi realizado um ensaio de adsorção com o efluente de curtume sintético. A remoção máxima de Cr(VI) no efluente sintético de curtume ficou em torno dos 90% para o biossorvente não modificado. Também o adsorvente não modificado foi caracterizado, com uma maior área superficial e volume de poros. Além disso, os estudos do equilíbrio e cinética de adsorção demonstraram que o biossorvente não modificado possuiria uma superfície heterogênea, com possibilidade de múltiplos sítios de adsorção. Cineticamente foi demonstrado que a fisissorção e a quimissorção, agiram simultaneamente, justificando a rápida adsorção do Cr(VI) a biomassa. Dessa forma, o presente estudo demonstrou que a biomassa da vagem de LF não modificada pode ser utilizada como um biossorvente de Cr(VI), gerando uma possibilidade futura de ser aplicado a um efluente de curtume real. Ao desenvolver um adsorvente de Cr(VI) a partir de um material não convencional, composto pela biomassa da vagem de LF não modificada, o presente trabalho vem apresentar uma alternativa sustentável e de baixo custo ao processo de tratamento de efluentes.

“…In fact, recent publications have shown that biomass wastes can be used as solid adsorbents for removing pollutants from water by performing mild chemical modifications and taking advantage of their natural properties. , This type of utilization of biomass resources can also be amenable to carbon capture, as it is environmentally advantageous because it lowers processing costs and reduces carbon emissions arising from thermal decomposition methods.…”

This study delves into the potential advantage of utilizing crab shells as sustainable solid adsorbents for CO 2 capture, offering an environmentally friendly alternative to conventional porous adsorbents, such as zeolites, silicas, metal−organic frameworks (MOFs), and porous carbons. The investigation focuses on crab shell waste, which exhibits inherent natural porosity and Nbearing groups, making them promising candidates for CO 2 physisorption and chemisorption applications. Selective deproteinization and demineralization treatments were used to enhance textural properties while preserving the natural porous structure of the crab shells. The impact of deproteinization and demineralization treatments on CO 2 adsorption and speciation at the atomic scale, via solid-state NMR, and correlated findings with textural properties and biomass composition were investigated. The best-performing sample exhibits a surface area of 36 m 2 /g and a CO 2 adsorption capacity of 0.31 mmol/g at 1 bar and 298 K, representing gains of ∼3.5 and 2, respectively, compared to the pristine crab shell. These results underline the potential of fishing industry wastes as a cost-effective, renewable, and eco-friendly source to produce functional porous adsorbents.

“…The development of treatment systems for adsorption columns (continuous system), with a fixed bed made up of biomass that adsorbs heavy metals, is a way to have disruptive projects because this type of treatment system provides a practical application in wastewater treatment [27]. The Fick diffusion model has been used successfully to predict rupture curves, calibrate the inlet load, and comply with the discharge standards, being the main parameter to model and define the designs of treatment systems, allowing to establish the operation time in which the column is saturated under certain operating conditions such as feed concentration, feed flow, and adsorbent mass [28][29][30][31][32]. One way to improve the removal of heavy metals on the biomass of E. crassipes is through their chemical or physical modification [28][29][30] to increase their affinity with the polluting agent molecules.…”

The impact generated by the indiscriminate disposal of heavy metals into the different bodies of water is not only environmental but also social due to the health effects it produces in several organisms, including ourselves. Therefore, treatment systems around the world are the subject of continuous research to find treatment systems that are economical, efficient, and easy to implement in the industries that generate these increasingly harmful impacts on society and the environment in general. One way to design and develop systems of water treatment is that which takes advantage of the waste generated, such as the waste from the E. crassipes plant. The conditions of this plant make it perfect due to its abundant biomass and important content of cellulose and hemicellulose. Nevertheless, in almost all the investigations that characterize the way in which the biomass of this plant adsorbs heavy metals, it does so under laboratory conditions, being very far from the reality of industrial discharges. The objective of this project is to design and develop a pilot-scale industrial wastewater treatment system with plant biomass and EDTA. Three pilot-scale systems were built with EDTA-modified biomass in different concentrations, giving the parameters of the design for the development of a system that can treat around 80 L of Chromium (VI) contaminated water. This treatment system with E. crassipes biomass and EDTA with proportions of 9:1 costs around USD 10, which is quite cheap compared to conventional ones.
