“…Tukey's HSD was employed by setting a significance level of 0.05 to assess whether there is a difference between the means of all potential pairs since the null hypothesis was rejected ( p -value < 0.05). 53,54 Based on the results, there were statistically significant differences ( p < 0.05) observed in the efficiency values across all tested pH, SA concentration, and resin dose values.…”

“…However, the effect of temperature was found to be insignificant for all resins tested, with a minimum p -value of 0.357. When the null hypothesis is rejected ( p -value < 0.05) in the one-way ANOVA, multiple comparison tests can be applied to determine whether there is a difference between the mean of all possible pairs. , This was carried out by using a posthoc test, namely, the Tukey test, by fixing the significance level as 0.05. Accordingly, the efficiency values were significantly different ( p < 0.05) for all pH values tested.…”

Itaconic acid (IA) has the potential to be one of the industry's most remarkable raw materials, but it must be recovered with high efficiency and selectivity from complex aqueous-based production media. In this study, three types of weak basic anion exchangers (WBAEs, Amberlite IRA-67, Lewatit MP-62, and Lewatit MP-64) and a strong basic anion exchanger (SBAE, Lewatit M-500) were tested for the separation of IA from aqueous solutions. The process was considerably affected by the operating pH, and the highest efficiencies were obtained at pH 3 and 4 with the WBAEs and SBAE, respectively. Equilibration was achieved in ∼60 min, and the data fitted the pseudo-second-order kinetic model for all resins tested. Decreasing yields with an increase in temperature confirmed the exothermic nature of the process. Isotherm curves demonstrated the consistency of the equilibrium data with Type I. The capacities increased with IA concentrations and decreased with resin doses. Lewatit MP-62 achieved the highest capacity (522.7 mg of IA/g of resin), and its performance was significantly better than those previously reported in the literature. The equilibrium data were in agreement with the Langmuir isotherm model; however, the R 2 values attained with the Freundlich and Temkin models were also relatively high, indicating the need for further isotherm analyses.

“…Still, all nanowebs exhibited significant linear fit to PSO, IDM, and EKM adsorption kinetic models (Table S1, Supporting Information). Additionally, Tukey's test was performed [ 79 ] (Figure 4b) to determine if PAN, 10% NC@PAN, and 20% NC@PAN were statistically significantly different from each other regarding CV adsorption over repeated cycles. Comparing 20% NC@PAN with PAN, p < 0.01 was obtained indicating that there is a substantial difference in CV adsorption performance between these two, whereas p = 0.021 when comparing 20% NC@PAN with 10% NC@PAN.…”

Lightweight, metal‐free, sustainable, and reusable adsorbent materials are of paramount significance in addressing the challenges of wastewater treatment. Accordingly, semi‐crystalline nanocellulose (NC) is extracted from tissue paper waste and used to modify polyacrylonitrile (PAN) to produce electrospun nanowebs with strand diameters from ≈180–300 nm. The incorporation of NC into PAN is confirmed by infrared and Raman spectroscopy and X‐Ray diffraction. When tested for crystal violet (CV) adsorption, NC‐modified PAN (20% NC@PAN) exhibits the highest CV removal capacity, achieving 91–94% removal over three cycles each, demonstrating exceptional recyclability. In contrast, unmodified PAN significantly decreases in CV adsorption capacity (from 59% to 48% in the third cycle), possibly due to an increased (≈36%) nanofiber diameter. The adsorption kinetics, exhibiting pseudo‐second order, interparticle (in between nanofibers) diffusion, and Elovich kinetic models emphasize the role of multilayer CV adsorption through reversible chemical interactions. Confocal micro‐Raman spectroscopy unveils a multifaceted CV adsorption mechanism, suggesting both surface and multilayer diffusion, with NC‐enhancing interactions. These findings demonstrate the potential of NC‐modified PAN nanowebs as effective and environmentally sustainable adsorbents for removing CV from aqueous solutions, suggesting promising practical applications.
