This study investigated the degradation of tetracycline (TCN) antibiotic catalytic activation of periodate (PI, IO ) using a novel composite catalyst composed of green-synthesized magnetite nanoparticles supported on water lettuce-derived biochar (MWLB). Characterization results revealed that the magnetic biochar possessed a porous structure, abundant surface functional groups, and high carbon and iron contents. Compared to conventional oxidants such as persulfate, hydrogen peroxide, and peroxymonosulfate, the PI-activated system demonstrated superior degradation efficiency.

Methods: Fifty patients undergoing mid-third clavicular procedures were randomly assigned to the ST group (received an SCN block followed by blockage of the ST of the brachial plexus) and the CFP group (received an SCN block followed by the CFP block). The primary outcome was the time until the first rescue analgesia.
This study presents novel composites of biochar (BC) derived from spinach stalks and zinc oxide (ZnO) synthesized from water hyacinth to be used for the first time in a hybrid system for activating persulfate (PS) with photocatalysis for the degradation of bromothymol blue (BTB) dye. The BC/ZnO composites were characterized using innovative techniques. BC/ZnO (2:1) showed the highest photocatalytic performance and BC/ZnO (2:1)@(PS + light) system attained BTB degradation efficiency of 89.

Thorough analyses were conducted to characterize the physical and chemical properties of the biochar. The (BC + light)/PS system exhibited superior MB degradation efficiency at 83.

The chemical and physical properties of the synthesized catalysts were analyzed using advanced techniques. ZnO/FeO-NC nanohybrid with mass ratio 1:2, respectively in the presence of PS showed the highest TCN removal efficiency compared to the individual components (ZnO and FeO-NC) and other nanohybrids with mass ratios of 1:1 and 2:1.
