Summary: This research investigates the kinetics of lac dye adsorption on eri silk yarn to improve village-based dyeing procedures, revealing an increase in adsorption rate and diffusion coefficient with temperature. Different shades of color on the silk yarn were achieved by changing mordants, with significantly improved wash and light fastness properties through post-mordanting.

Summary: This study explored the uptake behavior of acid dye molecules on silk fabric under laminar flow conditions. The effects of coloration liquid Reynolds number and velocity distribution on dye uptake were investigated and optimized. The results showed that controlling the flow of coloration liquid in laminar flow was beneficial for protecting the substrate, improving dye utilization, shortening coloration duration, and reducing pollutant discharge, thus achieving an efficient, energy conservation, and cleaner coloration process.

Summary: This study explored the adsorption of Congo red dye from textile effluent using natural clay glauconite as a sustainable and inexpensive adsorbent. The effects of varying concentrations of sodium hydroxide on glauconite alteration were examined, and the optimal NaOH concentration that improves removal efficiency and adsorption capacity was determined. The results showed that the CR removal efficiency increased with modification up to a 2 M NaOH activation. The analysis of kinetics and isotherms of CR adsorption revealed that the Freundlich isotherm closely matched the experimental results, and the pseudo-second-order model explained the obtained results accurately. The investigation on reusability demonstrated that the adsorbents could be efficiently reused. Overall, glauconite and its NaOH-activated forms are effective and affordable adsorbents for removing CR from textile effluent.

Summary: This study characterized the capacity of silk fibroin hydrogels to absorb dyes and investigated the effect of different pH and ionic environments on pre-treated hydrogels. The hydrogels exhibited absorption ability for cationic dyes, while showing opposite behavior for anionic dyes. Regeneration of the hydrogel was achieved by immersion in acidic pH, and when coupled with gold nanoparticle catalyst, it demonstrated the ability to absorb and catalyze dye reduction.

Summary: The extensive use of dyes leads to massive dye discharge in wastewater, causing water pollution. Plant-derived wastes are proposed as sustainable adsorbents for dye separation, but they are less effective for anionic dyes. The modification of these wastes to suit anionic dye removal has gained attention in recent years.

Summary: Biosorption using a chitosan-pectinase blend (CPB) was studied for the removal of methylene blue (MB) dye from synthetic solutions. The blend showed a rough surface morphology and amorphous nature. Fourier-transform infrared (FTIR) analysis confirmed the successful blend formation. Maximum adsorption was achieved at pH 7.0, 30°C, 30 min contact time, and an adsorbent dosage of 2.5 g/L. The pseudo-second-order model provided the best fit, with the highest R2 value close to 1. The Temkin isotherm model showed the highest adsorption capacity at 16.81 mg/g. The blend demonstrated good desorption ability, allowing for reuse in dye removal.
