Summary: Nanomaterials, specifically polypyrrole nanotube incorporated sodium alginate, showed promising results in the adsorptive removal of methylene blue dye from aqueous solution. The Langmuir isotherm model was found to be the most suitable in describing the adsorption process, with a maximum adsorption capacity of 666.7 mg/g at pH=7 and 25 degrees C. Additionally, the adsorption followed the pseudo-second-order kinetic model and occurred exothermically and spontaneously based on the thermodynamic parameters.

Summary: Understanding how to develop highly efficient and robust adsorbents for the removal of organic dyes in wastewater is crucial in the face of rapid industrialization. In this study, d-Ti3C2Tx nanosheets (MXene) were combined with sodium alginate (SA) to create SA/MXene nanofiber membranes (NMs) using electrospinning and Ca2+-mediated crosslinking. The NMs with an optimum MXene content of 0.74 wt.% exhibited a high adsorption capacity for methylene blue (MB) and excellent reusability.

Summary: Dye pollution is a serious issue in environmental protection. Bio-based adsorbents have gained attention for wastewater treatment due to their low cost, renewability, and environmentally friendly characteristics. This study fabricated bio-based SA/Lig hydrogel beads and investigated their adsorption properties for methylene blue (MB) removal. The results showed that the inclusion of lignin improved the thermal stability and adsorption performance of the composite material.

Summary: This study investigated the removal of basic dye methylene blue by adsorption onto low-cost sodium alginate-kaolin beads. The research developed three models and used two intelligent modeling techniques to describe the adsorption as a function of operating parameters, finding that the artificial neural network (ANN) model was the best in predicting dye removal efficiency.

Summary: Bio-based adsorbents were developed to remove dye contaminants for sustainable development. Aromatic bio-based tannin was incorporated into pure sodium alginate adsorbent to enhance its adsorption capacity. The Tan/SA composite hydrogel beads showed millimeter-sized beads with enhanced thermal stability. The 40% Tan/SA adsorbents achieved a maximum capacity of 247.2 mg/g at optimal conditions (pH = 12, T = 45 degrees C) with a removal efficiency of 82.4%. The adsorption process was endothermic and showed chemical adsorption, with a removal efficiency exceeding 90% after five cycles.

Summary: Methylene blue dye can cause serious damage to aquatic and human life when discharged into water bodies without proper treatment. Electrochemical methods have shown promise in removing dyes from water, thanks to their rapid response, cost-effectiveness, selectivity, portability, and simplicity. Quartz crystal microbalance nanosensors based on green synthesized magnesium ferrite nanoparticles and magnesium ferrite nanoparticles coated alginate hydrogel nanocomposite were designed for real-time detection of high concentrations of methylene blue dye in water. These nanosensors demonstrated great potential in dealing with continuous feed, small volumes, high concentrations of methylene blue, and providing an instantaneous response.
