UV-Vis spectroscopy (Optizen 2120UV, Mecasys Co., Daejeon, Korea) was used to measure the optical density (OD) of the supernatant of each of the samples (the sampling height was 2/3 of the tube from the bottom). The harvesting efficiency (%) was evaluated by the equation [12]: ...
for the degradation of naproxen: characterization and optimization using response surface methodology Masoud Habibi Zare* & Arjomand Mehrabani‑Zeinabad In this study, ZrO2, TiO2, and Fe3O4 components were synthesized by co-precipitation, sol–gel, and co-precipitation...
Dried biomass has an aptitude for eliminating heavy metals from bodies of water, such as Cd, Pb, Hg, and Co, by biosorption [35]. Spirogyra sp. is a rich source of antioxidants because of various phytochemicals, such as terpenoids, saponins, tannins, and flavonoids [22]. Ajuga bracteosa...
Co. (Wuhan, China). The water used in the experiments had been pretreated with an ultrapure water system (Liyuan Electric Instrument Co., Beijing, China). 3.2. Synthesis of REC/Fe3O4/ZnO 3.2.1. Synthesis of Magnetic REC Fe3O4 was prepared by a co-precipitation method as follows. A ...
The oxygen elements in the diagram can be fitted to four different types: lattice oxygen (O2−), OH−/CO32−, adsorbed (O−/O2−) [33,34], and adsorbed water. After comparison, it can be found that when Fe3O4 and LaNiO3 are compounded to form Fe3O4/LaNiO3 composites, ...
Thus, urea (CO(NH2)2) was used as a base instead of NH4OH. The slow hydrolytic degradation of urea in acidic conditions generated ammonia (NH3), which increased the reaction pH very slowly, leading to the precipitation of large Fe3O4 nanoparticles. The reaction vessel was a 100 mL Duran...
