“…56 These extracts can be utilized directly as coagulants and occulants, or they can be rened through a range of techniques, including ltration or centrifugation. 28,32 The effective use of these extractions depends on their characteristics, which need to be characterized and optimized for efficient applications. Characterization involves various techniques, such as Scanning electron microscopes (SEM), Energydispersive X-ray spectroscopy (EDS) analysis, and Fourier transform infrared (FTIR) spectroscopy, which are used to analyze the morphology, composition, and functional groups of natural coagulants and occulants.…”

“…Adding C/F with certain physical and chemical characteristics to wastewater might therefore improve coagulation performance and oc aggregation. 24,32 The mixing time could also inuence the rate and completeness of the reaction. It must be sufficient to guarantee that the C/Fs are thoroughly dispersed in the wastewater and that the particles have sufficient time to destabilize and agglomerate.…”

“…Additionally, the use of chemical coagulants/flocculants often generates a significant volume of sludge, increasing the cost of disposing of potentially hazardous sludge. 32 Due to the negative impacts of chemical coagulants/flocculants on the environment and human health, recent research has focused on identifying alternative options for achieving water clarity. As a result, an increasing focus is being placed on the advancement of NC/Fs as a more environmentally friendly and sustainable substitute for chemical coagulants/flocculants.…”

Frequent M. aeruginosa outbreaks pose a major risk to public health and have a detrimental effect on aquatic ecosystems. Researchers are looking into ways to stop and control M. aeruginosa blooms, a problem that affects both the aquatic environment and human health significantly. It is important to develop proper monitoring methods to identify M. aeruginosa blooms. However, the existing control and monitoring techniques have some drawbacks that limit the field’s applicability. Therefore, we must improve current methods for effectively monitoring and controlling M. aeruginosa blooms. Mitigation strategies should be customized for particular bodies of water utilizing techniques that are fast, economical, and field-applicable. This review critically identifies and evaluates green technologies, especially those focused on the presence of M. aeruginosa in freshwater, and compares and discusses problems with these green technologies. Furthermore, they were characterized and ranked according to their cost, effectiveness, and field applicability. A few suggestions for improvements were provided, along with ideas for future research projects that would take anticipated environmental changes into account.

Herein, a new heterogeneous catalytic system through modification of urea functionalized magnetic nanoparticles with choline chloride [Fe3O4@SiO2@urea-riched ligand/Ch-Cl] was designed and synthesized. Then, the synthesized Fe3O4@SiO2@urea-riched ligand/Ch-Cl was characterized by using FT-IR spectroscopy, FESEM, TEM, EDS-Mapping, TGA/DTG and VSM techniques. After that, the catalytic usage of Fe3O4@SiO2@urea-riched ligand/Ch-Cl was investigated for the synthesis of hybrid pyridines with sulfonate and/or indole moieties. Delightfully, the outcome was satisfactory and the applied strategy represents several advantages such as short reaction times, convenience of operation and relatively good yields of obtained products. Moreover, the catalytic behavior of several formal homogeneous DESs was investigated for the synthesis of target product. In addition, a cooperative vinylogous anomeric-based oxidation pathway was suggested as rational mechanism for the synthesis of new hybrid pyridines.
