Photocatalytic degradation of methylene blue and sulfisoxazole from water using biosynthesized zinc ferrite nanoparticles

Cobalt-substituted ZnS QDs: a diluted magnetic semiconductor and efficient photocatalyst

“…After exposure to radiation for a specific amount of time, the decrease in absorbance (at max = 270 nm) for drug samples showed the rate of degradation and, consequently, the effectiveness of the drug oxidation and photocatalytic effect of QDs. The degradation efficiency in percentage (%) was obtained using the following equation: 21–23 where C 0 is the initial CIP concentration and C is the concentration of CIP solution at a specific time t after the xenon light irradiation. Similarly, both A 0 and A t denote the initial and final absorbance of the CIP-containing solution obtained at the peak position ( λ = 270 nm) of the highest absorbance.…”

Role of Phytonanotechnology in the Removal of Water Contamination

“…The EPR spectrum detected the para magnetism of the NPs. The optimum pH was 12, and the total removal of sulfisoxazole was 67% in 120 min following the pseudo-second order [30].…”

Degradation of sulfadiazine in aqueous media by peroxymonosulfate activated with biochar-supported ZnFe2O4 in combination with visible light in an internal loop-lift reactor

“…ZnFe/BC was synthesized by a hydrothermal method. 46,47 BC (1 g) was fully dispersed in deionized water (80 mL) in a beaker with the aid of ultrasonication. ZnCl 2 (10 mmol) and FeCl 3 (20 mmol) were then added and the mixture was stirred for 100 rpm by means of a mechanical agitator (Eurostar 20 Digital, IKA RW20, Germany) for 20 min.…”
