[ 1 ] - جذب کادمیم در سطح نانو‌ذرات دی‌اکسید‌تیتانیم در سوسپانسیون های خاک
در این مطالعه برخی عوامل مؤثر در میزان جذب کادمیم در سطح نانو‌ذرات دی‌اکسید‌تیتانیم در خاک و پایداری نانو‌ذرات در سوسپانسیون‌های خاک مورد بررسی قرار گرفته است. نتایج این مطالعه نشان داد که در خاک آلوده به کادمیم در محیط سوسپانسیون، مقدار تثبیت کادمیم توسط نانو‌ذرات که به جذب کادمیم در سطح نانو‌ذرات نسبت داده می‌شود، به نسبت خاک‌به‌آب (1:20، 1:10 و 1:5)، میزان آلودگی خاک به کادمیم (5 و 10 میلی...
[ 2 ] - Sono-synthesis of Novel Magnetic Nanocomposite (Ba-α-Bi2O3-γ-Fe2O3) for the Solar Mineralization of Amoxicillin in an Aqueous Solution
In this study, a novel magnetic nanocomposite (Ba-α-Bi2O3-γ-Fe2O3) was successfully synthesized through a combination of ultrasound and co-precipitation method under mild conditions. The structure of the synthesized nano-composite as a visible light photocatalyst was investigated by the XRD, TEM, HRTEM, UV-vis and FT-IR. The HRTEM confirmed that the nano-magnetic composites are rods with diamet...
[ 3 ] - Quantum dots of CdS synthesized by micro-emulsion under ultrasound: size distribution and growth kinetics
Quantum dots of CdS with hexagonal phase were prepared at relatively low temperature (60 oC) and short time by micro-emulsion (O/W) under ultrasound. This study was focused on the particle size distribution and the growth kinetics. The particle size distribution obtained from the optical absorption edge. It was relatively symmetrical with sonication time. In addition, an agreement was observed ...
[ 4 ] - Solar Photocatalytic Degradation of Diclofenac by N-Doped TiO2 Nanoparticles Synthesized by Ultrasound
Anatase N-doped TiO2 nanoparticles were synthesized using ultrasound at low frequency and room temperature. The samples characterized by techniques including XRD, TEM, HRTEM, FT-IR, XPS, and UV–Vis spectroscopy. XPS indicated the existence of nitrogen as an anion dopant within the TiO2 lattice. The solar photocatalytic activity of N-doped TiO2 studied for th...
