Summary: This study investigated the ability of algae to decolorize and remove synthetic dyes. Spectral analysis showed increased efficiency for color degradation by the tested algae. Chlorococcum sp. exhibited the most drastic reduction in absorbance on the 5th day and had higher laccase enzyme production. The study also evaluated the toxicity of Congo red dye on fish and found that Chlorococcum sp. could be a potential candidate for dye effluent treatment.

Summary: The treatment of wastewater containing synthetic dyes is crucial due to their potential risks to the environment and public health. Adsorption process using interpenetrating polymer networks (IPNs) and semi-IPNs hydrogels as adsorbents have gained attention for their stability, high swelling capacity, non-toxicity, biocompatibility, and biodegradability. This review examines the removal of synthetic dyes from aqueous media using semi-IPNs and IPNs hydrogels, discussing their preparation, adsorption capacities, and future perspectives.

Summary: In this study, Mn-Fe LDH/CS composite was successfully prepared and used for the simultaneous removal of IC and SY dyes. The first order derivative spectrophotometric method was applied to measure IC and SY simultaneously, and the pseudo second order model was found to be the best fitting model under the optimum conditions. The adsorption isotherm of dyes followed the Langmuir isotherm model.

Summary: In this study, Hormophysa trique-tra (HT) and its silver-modified form (AgHT) were used for the removal of Crystal violet (CV) from synthetic and real wastewater. The optimal pH for the adsorption process was found to be 6, with maximum adsorption capacities of 181.8 mg/g for HT and 312.5 mg/g for AgHT at 45 degrees C. This study demonstrates the potential of using naturally abundant macroalgae as an environmentally friendly and successful green technology for the removal of CV from real wastewater.

Summary: The study investigated the adsorption effect of freshly formed ferric hydroxide on various synthetic dye and antibiotic wastewaters under different pH conditions. It was found that the surface properties of FFFH, such as high specific surface area and abundant hydroxyl groups, contributed to its adsorption capacity. The establishment of QSAR models further revealed the intrinsic factors influencing the removal rates at the molecular structure level, indicating the stability and reliability of the models.

Summary: The study synthesized graphene oxide crosslinked nanocomposites hydrogels of chitosan and carboxymethyl cellulose as versatile adsorbents for both cationic and anionic dyes contaminated wastewater. The adsorption process was well explained using pseudo-second-order and Langmuir models, with excellent regeneration capacity demonstrated for continuous cycles of adsorption-desorption. The synthesized CS/CMC-NCH showed great potential for effective treatment of dye-contaminated wastewater.
