Degradation of microcystin-LR using functional clay supported bimetallic Fe/Pd nanoparticles based on adsorption and reduction

Catalytic degradation of Orange II in aqueous solution using diatomite-supported bimetallic Fe/Ni nanoparticles

“…The concentration of OII was measured spectrophotometrically using an Agilent Cary 60 UV-Vis Spectrophotometer by measuring absorbance at k max of 485 nm. The removal efficiency of OII using materials was calculated by eqn 3: 24 Moreover, the concentration of total organic carbon was measured by the use of a Shimadzu TOC-V total organic carbon analyser. The furnace was set to 720 C and the carrier gas was zero grade air.…”

“…[21][22][23] The porous structure also exhibits relatively high hydraulic conductivity which transfers contaminants to reactive sites, thereby increasing removal efficiency. 21 To date, only a few studies have reported the use of claysupported bimetallic nanocomposites for the remediation of contaminated aqueous solutions, 20,[24][25][26][27][28] while, to the best of our knowledge, diatomite-supported bimetallic nanocomposite has not been reported for the catalytic removal of organic contaminants. Therefore, the aim of this project is to create a novel diatomite-supported Fe/Ni (Di-Fe/Ni) composite material, which has high reactivity and efficiency for the removal of the azo dye Orange II (Acid Orange 7) as a model of organic contaminant.…”

Reduction in smoke emitted and fire hazard presented by flexible poly (vinyl chloride) through novel synthesis of SnO2 supported by activated carbon spheres

“…The dispersibility and surface area of compounds containing tin can be enhanced by using the support materials. The support material usually used include clay, 16 pumice, 17 kaolin, 18 resin, and carbon materials. 19 Recently, the use of AC has been explored not only as a carbon source, but also as an efficient catalyst for the removal of HCl.…”

Degradation of the Reactive Blue 4 Dye in Aqueous Solution Using Zero-Valent Copper Nanoparticles

“…This conclusion is in agreement with Zhou et al [47], who consider degradation reactions can be kinetically controlled by the mass transfer process (e.g., diffusion of the surface reagent) or by the chemical adsorption on the nanoparticles surface. In the first case, activation energy values were between 8 and 21 kJ mol −1 , while higher values (generally above 29 kJ mol −1 ) are indicative of the second process [46][47][48].…”

“…After 10 minutes of reaction, the degradation rate already reached 71% when using a 30 ∘ C temperature, which was higher than the rates obtained at 25 ∘ C (65%), 20 ∘ C (62%), and 10 ∘ C (3%) during the same reaction time. Almost 30% more dye was degraded by raising the temperature from 25 ∘ C to 30 ∘ C. Endothermic reactions involving metallic nanoparticles have been observed in many studies present on the literature [41,45,46].…”
