Preparation of martite nanoparticles through high-energy planetary ball milling and its application toward simultaneous catalytic ozonation of two green algae

Cubic cobalt and zinc co-doped magnetite nanoparticles for persulfate and hydrogen peroxide activation towards the effective photodegradation of Sulfalene

“…The solution pH is one of the fundamental factors in the decomposition of the target pollutant [27]. Before performing the experiments related to this section, the point of zero charge of Fe 2.5 Co 0.3 Zn 0.2 O 4 nanoparticles, the adsorption of SFL in the different pH values, and finally the pk a were studied and presented in Fig.…”

“…Fig. 3b, the efficient catalyst in the presence of UVA resulted in the highest PS activation and consequently the synergy factor ( In the literature, the existence of the synergy effect was reported as proof of the high-performance process for the degradation of various water pollutants[21,27]. The main reason for the presence of the synergy factor and efficient SFL degradation to a greater extent can be related to the positive impact of the UVA-light and co-doped magnetite in the activation of persulfate.…”

Synthesis of a magnetically separable LDH-based S-scheme nano-heterojunction for the activation of peroxymonosulfate towards the efficient visible-light photodegradation of diethyl phthalate

“…For further studying, we used the attained k app for the calculation of the synergy factor for different methods of PMS activation. Accordingly, by applying the following equations [22,51] the synergy factors of PMS/Vis-light, PMS/composite, and PMS/Vis-light/composite processes were determined to be 0.1, 8, and 14, respectively. ynergy factor…”

Inactivation of harmful algal bloom by an environmentally friendly photocatalyst under photo-Fenton-like degradation process

“…Diatoms, dinoflagellates, cyanobacteria, and green algal cells like Scenedesmus quadricauda are the critical classes of organisms that produce algal blooms. Though diatoms and dinoflagellates are commonly found in seawater blooms, cyanobacteria and green algal cells thrive in freshwater (Khataee et al, 2018a(Khataee et al, , 2018bPaerl, 2009;Zou et al, 2020).…”

“…and Cosmarium sp.) (Khataee et al, 2018a), as well as diatoms (Nitzschia sp.) (Khataee et al, 2018b) in the surface water.…”
