methylene blue is widely used in various industrial branches. due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. hydroponic experiments were conducted with rice seedlings (oryza sativa l. cv. xzx 45) exposed to methylene blue to determine the effective concentration using relative growth rate...

Advanced oxidation processes (AOPs) are considered highly competitive water treatment technologies for the removal of organic pollutants. Among AOP techniques, photocatalysis has recently been the most widely studied. Our aims were to investigate how the dispersion of nanosized titanium dioxide (nanoTiO2) applied in photodegradation-based procedures can be stabilized with cyclodextrins in order...

Novel ternary nanocomposite photocatalysts based on g-C3N4/Fe3O4/TiO2 nanosheet were synthesized using simple solid combustion, hydrothermal and wetness impregnation methods. The g-C3N4 nanosheet (2D)/ Fe3O4/ TiO2 nanosheet (2D) triad-interface nanocomposite arranged in the form of Fe3O4 nanoparticle was sandwiched and well dispersed on the surface between g-C3N4 and TiO2 nanosheets. The synthe...

In this study, the photocatalytic and bleaching properties of pure and doped titanium dioxide nanoparticles with 1%, 3%, 5% and 10% Ce dopant were studied using Ce(NO3)3 precursor. The results showed that the highest methylene blue degradation of the sample with 5% cerium impurity was 97% in neutral medium (pH=7) after 75 minutes. The bleaching response to wastewater treatment with 5% cerium im...

In this paper, the photosensitive Zr-MOF material Thiadiazole-modified UiO-68 (UiO-68N2S) was used to prepare CdS@UiO-68N2S composites by MOF post-reaction. The chemical composition is characterized using PXRD, FT-IR, XPS, SEM, and TGA. Rhodamine B as model dye for photocatalytic degradation evaluate performance of under visible light irradiation. Experimental results show that rate a 25 mg/L R...

In the current survey, the removal of dye from contaminated water was studied by photocatalytic degradation using TiO2 nanoparticles with respect to pH, TiO2 dosage, reaction time, temperature and initial dye concentration. TiO2 nanoparticles were investigated by XRD, FESEM and FT-IR.The RSM was chosen to study the composition effects of input independent factor...
