Summary: This study investigated the biodegradation of the azo dye AB113 and identified the key pathways and enzymes involved in its degradation. The results showed that the benzoate and naphthalene degradation pathways played a crucial role in AB113 degradation, and enzymes such as NADH quinone oxidoreductase, N-acetyltransferase, aromatic ring-hydroxylating dioxygenase, and CYP450 were found to be important for AB113 degradation.

Summary: Conjugated porous polymers (CPPs) are a new family of functional porous materials with tuneable porosities and molecular architectures, showing great potentials in adsorption, light harvesting, and catalysis applications. This study describes the incorporation of strong visible-light absorbing BODIPY molecules into the skeleton of CPPs, resulting in CPPs with integrated properties of high surface area, hierarchical porous structures, and strong visible-light absorption. The obtained CPPs demonstrated relatively high adsorption capacity and high photocatalytic degradation efficiency towards organic dyes, with mechanism studies revealing the generation of singlet oxygen species as the main driving force for the dye degradation.

Summary: Dye wastewater from industries is causing serious environmental problems. Adsorption technology has emerged as a promising method for dye wastewater treatment in the past decade. We developed two kinds of magnetic porous adsorbents (HSF and HSVF) with different specific surface areas and activity sites. Both adsorbents showed excellent performance in terms of dye adsorption capacity, especially HSVF. The adsorption kinetics and isotherms were further studied and compared, revealing that introducing strong active sites can improve adsorption capacity and rate. This research highlights the significance of adsorption technology for treating dye wastewater.

Summary: The objective of this study is to investigate the use of sludge from drinking water treatment plants as an adsorbent for removing methylene blue (MB) dye from contaminated water. Chemical activation of the used sludge was performed to create new adsorbents using HCl, H2O2, and a mixture of HCl and H2O2. Various boundary conditions, such as initial dye concentration, adsorbent dosage, solution pH, contact time, and temperature, were tested to determine the optimum operational conditions. The results showed that sludge activated by a 2:1 mixture of HCl/H2O2 was the most effective adsorbent, achieving a 99.9% removal rate. The best MB adsorption results were obtained with an initial dye concentration of 50 ppm, a contact time of 90 minutes, a pH of 7, and an adsorbent dosage of 0.25 g. The Langmuir and Freundlich models fit well with the adsorption behavior of the adsorbents.

Summary: Adsorption is a cost-effective method for removing pollutants from water, and clay minerals can be converted into biosorbents for this purpose. This review article summarizes the structure, properties, and applications of different types of natural clays, as well as the process and mechanism of adsorption of heavy metals and toxic dyes. The Langmuir and Freundlich models are commonly used for isotherm analysis, and the majority of adsorption kinetics studies are based on the pseudo-second-order model. Modifying clays can improve their adsorption efficiency, and these materials are environmentally friendly and beneficial for industrial ecology.

Summary: In this study, magnetic hybrid clay CT@Fe3O4 was synthesized for wastewater treatment using a straightforward and efficient method. The adsorbents were characterized and evaluated, showing a significant increase in surface area and pore volume compared to raw clay. The adsorption performance of CT@Fe3O4 for AB113 dye was studied in batch and fixed-bed column adsorption experiments, revealing its superior adsorption capacity. Kinetic modeling and analysis suggested that the Thomas and Yoon-Nelson models offered a more accurate explanation of the experimental outcomes. The adsorption mechanism of CT@Fe3O4 was found to involve multiple interactions. Overall, CT@Fe3O4 proved to be a suitable and effective adsorbent for the sequestration of AB113 dye from aqueous solutions.
