a floating polymer-supported photocatalyst based on polystyrene impregnated with titaniumdioxide particles was developed using a facile solvent-cast method at ambient temperature. the preparedphotocatalysts were characterized by x-ray diffraction, scanning electron microscopy and fourier transforminfrared spectroscopy. the photocatalytic activity of the developed photocatalysts was investigated...

OBJECTIVES Cultural variability (CV) is introduced as an overlooked dimension of cultural identity development pertaining to emphasizing and de-emphasizing the influence of a single cultural identity (i.e., cultural influence [CI]) on daily interactions and behaviors. The Cultural IDentity Influence Measure (CIDIM) is introduced as a novel measure of CI and CV, and hypothesis-driven validation ...

this study evaluates the effectiveness of adsorption process by granular activated carbon (gac) compared with a novel formulation of coagulation - flocculation process for dye removal from textile wastewater. in this regard, acidic, reactive, disperse and direct red dye are used to prepare the synthetic dye. dominant wave length for each dye is determined by spectrophotometeric method. using ga...

The color images raise the level of educational by providing more detailed information; therefore, these images are believed to be effective in gaining a deeper understanding of the lessons. Moreover, Proper lighting enhances students’ learning and performance. This study aimed at assessing the impact of training color and light materials on elementary school girls’ attention and learning in Pe...

Pseudomonas otitidis WL-13, which has a high capacity to decolorize triphenylmethane dyes, was isolated from activated sludge obtained from a wastewater treatment plant of a dyeing industry. This strain exhibited a remarkable color-removal capability when tested against several triphenylmethane dyes under both shaking and static conditions at high concentrations of dyes. More than 95% of Malach...

The removal of color from synthetic wastewater containing Congo red was experimentally investigated using electrocoagulation process. The effects of operational parameters such as current density, electrolysis time, electrolyte concentration, electrode distance, initial dye concentration, initial pH and temperature on color removal efficiency were investigated in this study. The tentative resul...

This work assesses the efficiency of integrated enhanced coagulation and direct filtration processes for the removal of color, turbidity, and natural organic matter (NOM) from surface water. The processes were conducted in a simulated pilot. The operating conditions of the treatment process, including pH, FeCl3 dose, and influent flow, were investigated. Following that, its efficienc...
