“…When pH becomes 4 or 8, the dye removal decreases about 4.8% and 3.6%, respectively. Ghourbanpour et al [ 18 ] suggested a significantly larger effect of the pH on the efficiency of the dye removal for their developed PVA/Fe(III) and PVA/Chitin/Fe(III) adsorbents.…”

“…The values reported for Q m in the literature are in a wide range. While Othman et al [ 65 ] suggested 1666.67 mg/g for the removal of MB dye, Tharaneedhar et al [ 60 ] reported 82.71 mg/g and Gourbanpour et al [ 18 ] obtained 810.4 mg/g for their developed composite. For SF dye removal, Abukhadra et al [ 66 ] and Sahu et al [ 67 ] reported 65.35 and 89.47 mg/g, respectively.…”

A novel polyvinyl alcohol (PVA)/calcium carbonate-based double-layer cationic dye adsorbent was developed. Polyvinyl alcohol (50 wt %) and calcium carbonate (50 wt %) were used together with borax as a cross-linking agent. The nanocomposite was prepared using only water, without the need for any toxic solvent or hazardous chemical. The final samples were obtained by the solvent casting method. The nanocomposite adsorbent was characterized using a Fourier transform infrared (FTIR) spectroscope and a scanning electron microscope (SEM). The adsorption performance on two cationic dyes, i.e., methylene blue and safranin was studied. Dye adsorption was quantified by measuring the nanocomposite swelling, contact time, and dye concentration. Pseudo first-order and pseudo second-order kinetic models as well as intraparticle diffusion model were used to model the adsorption kinetics. Moreover, the isotherm dye adsorption was investigated by Langmuir and Freundlich models. The results revealed that the developed nanocomposite has relatively high adsorption efficiency and short adsorption time and retains its performance after several successive absorption–desorption processes. The results also showed that the pseudo-second-order model best describes the adsorption kinetics, and the Freundlich isotherm model has a better compatibility with the experimental data. Finally, an adsorption mechanism was proposed for the dye removal process. The developed PVA/CaCO3 nanocomposite can be potentially used for efficient dye removal in wastewater treatments.

Environmentally sustainable composite films were synthesized using polyvinyl alcohol (PVA) and cellulose. Cellulose was extracted from the Agro-waste (sugarcane bagasse) using chemical pre-treatment followed by the acid-hydrolysis process. The composites were also used for the treatment of dye (Methylene blue; MB and Crystal violet dye; CV) and it was observed that the removal capacity of PVA/C was 70% for CV and 64.5% for MB dye. The biodegradation study of these composite films was also carried out using bacterial strains isolated from the marine waters of south Bengal. The biodegradation study of these polymer composites was characterized by FTIR, SEM, XRD, TGA, swelling properties, and weight loss. The results indicated that the PVA/C polymer showed a better rate of degradation (43%) than PVA (35%). Different loading parameters like pH, temperature, and inoculum dosage were studied to assess the degradation of the composite materials. Thus, biodegradable composite films were synthesized utilizing Agro-waste and had dye removal properties.

In the present study, encapsulation was used as an efficient and rapid removal method for RB-250 from aqueous solutions. This technique involves the simultaneous formation of CMC particles and the entrapment of the anionic dye RB-250 within these particles. TEM and Zeta analyses of dye encapsulated CMC particles showed needle type agglomeration of particles. Various parameters were investigated to optimize the RB-250 removal efficiency of CMC by encapsulation. These studies revealed that temperature, pH, time and stirring rate have negligible effect on the encapsulation of RB-250. It is quite remarkable that pH, which is a parameter that significantly affects the removal efficiency in the removal of charged dyes, has a negligible effect in the proposed technique. RB-250 encapsulation capacity of CMC nanoparticles was determined as 2809 mg RB-250/g CMC.
