“…The issue can be mainly correlated to textile manufacturing, which is in constant evolution and activity, as recently reported in some reviews [34][35][36]. The problems caused by dyes fall in two main fields: environment (i.e., affecting the photosynthetic function in plants and eutrophication of aquatic life [37]) and human health [38].…”

“…Lastly, crystal violet is extensively used to dye different kinds of textiles and paper [42], to produce printing inks and represents a dermatological agent in veterinary medicine [43]. It is toxic, may be absorbed through the skin causing irritation and is harmful by inhalation and ingestion [38,43,44]. In extreme cases, it can lead to kidney failure, eye irritation until permanent blindness and cancer [38,43,44].…”

The growing utilization of renewable and residual biomasses for environmental preservation and remediation are important goals to be pursued to minimize the environmental impact of human activities. In this paper, sodium alginate (derived from brown algae) was crosslinked using chitosan (mainly derived from the exoskeleton of crustaceans) in the presence of biowaste-derived substances isolated from green compost (BBS-GC), to produce hydrogels and dried films. The obtained materials were tested as adsorbents for wastewater remediation. To this purpose, gels were characterized using a multi-analytical approach and used as active substrates for the removal of three differently-charged molecules, chosen as model pollutants: crystal violet, rhodamine B, and orange II. The effectiveness of the gel formulations was demonstrated and attributed to the variety of active functionalities introduced by the different precursors, the structural factors and the peculiar physicochemical properties of the resulting materials.

“…If there should be an occurrence of a nonlinear model, these isotherms demonstrated a lower relationship coefficient when contrasted with the straight model for altered items, as shown in Table 5. The chi-square (χ 2 ) test was used to confirm the proficiency and adjustment of the models, as reported in earlier studies [38]. The dissemination of error and chi-square test esteems were lower on the off chance that Langmuir isotherm type 1 fit the trial information better.…”

The present study reports the engineering of functionalized chitosan (CH)-based biosorbent material. Herein, a two-step reaction was performed to chemically modify the CH using 1,4-bis(3-aminopropyl) piperazine to incorporate nitrogen basic centers for cations sorption from the aqueous environment. The resultant functionalized chitosan-based sorbent material was designated as CH-ANP and characterized using various analytical techniques, including elemental analysis, Fourier-transform infrared spectroscopy (FTIR), 13C NMR (in solid-state), X-ray diffraction, and thermal analysis. Then, the newly engineered CH-ANP was employed for the removal of copper, lead, and cadmium in the aqueous medium. Langmuir sorption isotherm analysis revealed that the highest sorption abilities achieved were 2.82, 1.96, and 1.60 mmol g−1 for copper, cadmium, and lead, respectively. Linear and nonlinear regression methods were deployed on the sorption data to study the behavior of the Langmuir, the Freundlich, and the Temkin sorption isotherms. Among the four different forms, the Langmuir isotherm type 1 fit well to the experimental data as compared to the other models. It also showed the lowest values of error, and a higher correlation coefficient than the Freundlich and Temkin models; thus it was the best fit with the experimental data compared to the latter two models. In conclusion, the findings suggest that chemically modified novel materials with enhanced Lewis basic centers are useful and promising candidates for the sorption of various toxic cations in aqueous solution.

Eriochrome black adsorption on yellow passion fruit peel (Passiflora edulis f. Flavicarpa) treated with sodium hydroxide and nitric acid: study of adsorption isotherms, kinetic models and thermodynamic parameters

The yellow passion fruit peel was used for Eriochrome black adsorption studies in aqueous solution in such a way as to propose a use for this by-product of the Brazilian fruit juice industry. The passion fruit peel was treated with nitric acid and sodium hydroxide to simulate pectin removal conditions and provide surface modifications that enhance adsorption. The kinetics and equilibrium experiments were completed in batch, at room temperature and contact times from 15 to 240 min. The thermodynamic studies were accomplished through a 298-343 K temperature variation. The adsorption capacities ranged from 196 to 303 mg/g, with the NaOH-treated sample having the highest adsorption capacity at all temperatures. This result points out that the passion fruit peel is a promising adsorbent compared with other low-cost adsorbents. The adsorption process is exothermic and occurs with decreasing entropy. The spontaneity of the process is low except for the sample treated with NaOH. Gibbs free energies were − 1.70 kJ/mol for the untreated sample, − 2.55 kJ/ mol for the HNO3-treated sample, and − 6.03 kJ/mol for the NaOH-treated sample at room temperature. The thermodynamic studies have shown that Eriochrome black adsorption on passion fruit peel is a physical process. The process kinetics may be described by the pseudo-second-order model, with diffusion limitations in the solution. The results indicate that NaOH-treated passion fruit peel is a promising adsorbent for Eriochrome black and may be used to adsorb other acid dyes in aqueous medium.Keywords Passion fruit peel · Acid dye adsorption · Low-cost adsorbents · Fruit peel treatment · Modified passion fruit peel · Isotherm comparison Mathematical Subject Classification 92E99 JEL Classification Q250 and Q530
