“…As a polymer, alginate has many carboxyl and hydroxyl groups, giving it a high affinity for radionuclides and metals. 79 However, scientists are very interested in learning more about synthesizing alginate derivatives via surface functionalization to advance their stability and mechanical strength for use in environmentally friendly applications. In most cases, you can functionalize alginate in one of two ways.…”

“…Sodium alginate is a linear copolymer of β-D-mannuronic acid (M) residues, linked with α-L-guluronic acid (G) through 1,4-glycosidic bonds. The residues can form a homopolymer composed solely of one type of monosaccharide or heteropolymer blocks constructed from both types [ 34 , 35 , 36 , 37 ]. Alginates are natural polysaccharides produced by bacteria or extracted from brown algae, which consist of β-D-mannuronate (M blocks) and α-L-guluronate (G blocks) linked with 1→4 bonds.…”

In the quest for advanced and environmentally friendly solutions to address challenges in the field of wastewater treatment, the use of polymers such as sodium alginate (Na-Alg) in combination with immobilized microorganisms (IMs) stands out as a promising strategy. This study assesses the potential of Na-Alg in immobilizing microorganisms for wastewater treatment, emphasizing its effectiveness and relevance in environmental preservation through the use of IMs. Advances in IMs are examined, and the interactions between these microorganisms and Na-Alg as the immobilization support are highlighted. Additionally, models for studying the kinetic degradation of contaminants and the importance of oxygen supply to IMs are detailed. The combination of Na-Alg with IMs shows promise in the context of improving water quality, preserving ecological balance, and addressing climate change, but further research is required to overcome the identified challenges. Additional areas to explore are discussed, which are expected to contribute to the innovation of relevant systems.

This comprehensive review explores recent advancements in immobilization strategies for graphitic carbon nitride (g-C3N4), a metal-free photocatalyst that has gained significant attention for its optical and physicochemical properties comparable to traditional photocatalysts like TiO2. However, a critical challenge regarding their application has emerged from the difficulty of its recovery due to its powdery nature. Therefore, several alternatives are being explored to immobilize this material, facilitating its recovery and reuse. This review systematically categorizes various physical and chemical immobilization techniques, providing an in-depth analysis of their advantages, drawbacks, and applications. Techniques such as encapsulation, electrospinning, casting, and coating, along with their adaptations for g-C3N4, are thoroughly examined. Additionally, the impact of these strategies on enhancing the photocatalytic efficiency and operational stability of g-C3N4, particularly in environmental applications, is also assessed. Thus, this review aims to provide valuable insights and guide future research in the realms of photocatalysis and environmental remediation. The review contributes to the understanding of how immobilization strategies can optimize the performance of g-C3N4, furthering its potential applications in sustainable and efficient environmental solutions.
