Biosynthesis of iron oxide nanoparticles for the degradation of methylene blue dye, sulfisoxazole antibiotic and removal of bacteria from real water

Green synthesis of gold nanoparticles using macroalgae Halimeda macroloba extract and their photocatalytic degradation of methylene blue and methyl orange

“…The removal of dyes has been accomplished by the use of a variety of techniques, including flotation, ion exchange, osmosis, chlorination, adsorption, electrochemical transformation, biosorption, and photocatalytic destruction 8 . These techniques are not only costly but also need delicate apparatus, and the items that are produced cannot be reused.…”

“…These techniques are not only costly but also need delicate apparatus, and the items that are produced cannot be reused. Among these strategies, photocatalysis is the one that researchers like the most since it has been shown to be effective in the degradation of complex pollutants, it is simple to implement, and it can provide results that are repeatable 8 . Nanotechnology usually comprises nanoparticles ranging from 1 to 100 nm 9 .…”

Carbonized Waste Cation Exchange Resin with Fe Doping for Persulfate Activation and Oxytetracycline Degradation: Performance and Mechanism

“…[10,11]. Fe-based activator has attracted much attention due to their low toxicity, geological reserves, and easy recovery, such as zero-valent iron [12], Fe 3 O 4 [13], Fe-Fe 2 O 3 [14], Fe-carbon [15], etc. Fe-carbon materials could be used as activators by being prepared from various carbon precursors, such as coconut shells [16], balsa woods [17], and waste resins [18].…”
