“…One of the factors that were assessed in this research is the initial concentration of dye. The Initial concentration is an indicator to identify whether the adsorption process of dye happens in multilayers or monolayers [30]. Five levels of initial concentrations of methylene blue were employed in this study 20, 40, 60, 80, and 100 mg/l at a fixed adsorbent dose which was 0.1gm.…”

The AgNPs-IPN's has been successfully prepared by synthesized biosynthesis of Ag nanoparticles (AgNPs) from Zizyphus Spina Christi L leaves extract and then linked with polymer network derived from cured epoxy with lignin to produce (AgNPs-IPN's) and characterized by using X-Ray, FTIR, TGA, DTG, SEM, and TEM surface morphology analysis and then used as adsorbent of methylene blue dye from synthetic wastewater. Parameter like pH, contact time, methylene blue concentration, and adsorbent dose concentration was studied. Methylene blue removal increased when the dosage of biosorbent increases. Isotherm adsorption was also described by the Langmuir and Freundleich models, It was found that Langmuir isotherm (R 2 = 0.9956) is better than the Freundlich model (R 2 = 0.9937) which implies that the adsorption of MB on AgNPs-IPN's was monolayer. Thus the maximum adsorption capacities calculated from the Langmuir model was found to be 33.5 mg.g −1 and was consistent with the experimental data. The synthesized AgNPs-IPN's showed an excellent activity towards the removal of methylene blue from synthetic wastewater.

“…The discharge of colored synthetic dyes such as methylene blue (MB) dye is visually invasive and can cause a water body by hindering light penetration as well as oxygen dissipation [88,89]. Therefore, to resolve this problem, researchers have considered carbon materials as an adsorbent to remove the organic and inorganic contaminants from the water [86]. Lemos and colleagues used chrysotile-CNT (discussed in Section 2.3) composites for turbidity removal from biodiesel wastewater and in methylene blue (MB) solutions discoloration by using a heterogeneous Fenton-like process [62].…”

This review sums up the techniques used for the synthesis of carbon nanotubes (CNTs), carbon nanofibers (CNFs), and carbon nanospheres (CNSs) by employing catalysts of natural origin. Establishing large-scale production and commercial applications of CNTs for a sustainable society is still of high apprehension. In this regard, one of the major factors is the starting materials such as precursors and catalyst sources. However, natural materials contain a minor quantity of metals or metal oxides and could be employed as a catalyst source for the synthesis of CNTs, providing the possibility to replace expensive catalyst sources. A large number of successful studies have been completed so far and confirm that these developed methods for carbon nanomaterials synthesis exhibiting high quality from common natural materials are not only possible but, most importantly, promising and scalable. This review also highlights purification methods and recent promising applications of as-synthesized CNTs.

“…Over the years, researchers have explored the use of agricultural wastes, such as rice husk, wheat straw, rice peel, sugar cane bagasse, orange peel, and garlic peel, for dye removal [61][62][63][64]. Naturally occurring fber-based materials, including cotton fbers, kapok, kenaf core, and palm kernel, have also been investigated as adsorbents for dye removal [65][66][67][68].…”

In this research endeavor, we sought to enhance the efficacy of bamboo fibers through modification with the surfactant cetyltrimethylammonium bromide (CTAB) for the purpose of removing Reactive Blue 235 from effluent. Our investigation encompassed a comprehensive exploration of the impact of crucial parameters, namely, adsorbent dosage (0.25 g–1.25 g), contact time (10–80 min), pH (2–12), initial dye concentration (20–100 mg/L), and temperature (298 K, 308 K, and 318 K) on the dynamics of dye removal. The optimum dye removal efficiency of 94% for Reactive Blue 235 was obtained at an adsorbent dosage of 0.5 g/50 ml of dye solution, initial dye concentration of 40 mg/L, pH of 6, and contact time of 40 min. The experimental framework included the anticipation of data aligned with various isothermal and kinetic models, facilitating a nuanced understanding of the adsorption process. Our findings unveiled that the kinetics of adsorption adhered to a second-order model, while the Langmuir isotherm model aptly described the adsorption behavior. Particularly noteworthy was the monolayer’s adsorption capacity, quantified at an impressive 7.39 mg·g−1 at a temperature of 318 K. The value of Freundlich’s constant, KF, increases with an increase in temperature indicating the endothermic nature of adsorption. The magnitude of E obtained from Dubinin–Radushkevich isotherm varying from 3.92 to 4.66 kJ/mol on increasing temperature from 298 K to 318 K suggests that adsorption of RB235 on BAT is a physisorption (value of E is between 1 and 8 kJ/mol). Delving into the thermodynamic aspects of the process, we calculated ΔH and ΔS to be 54.88 kJ/mol and 184.54 J/mol/K, respectively. The consistently negative values of ΔG (between −0.183 kJ/mol and −3.884 kJ/mol) at all temperatures underscored the feasibility, spontaneity, and entropy-driven nature of the adsorption of RB235 on CTAB-treated bamboo fiber (BAT). What sets our study apart is the deliberate utilization of bamboo fibers sourced from local waste streams, embodying a commitment to sustainable practices. Beyond its effectiveness in effluent treatment, our approach aligns with eco-friendly principles by repurposing indigenous waste materials, contributing to a more sustainable and environmentally responsible future.
