stabilization of nanosized tio2 particles on knitted cotton/polyester fabric by citric acid for self-cleaning and discoloration of reactive black 5 from waste water

Degradation of Azo Dye Reactive Black 5 and Acid Orange 7 by Fenton-Like Mechanism

Equilibrium and Thermodynamics Studies for Decolorization of Reactive Black 5 by Adsorption onto Acid Modified Banana Leaf Ash

Abstract Background: At present study, acid modified banana leaf ash was used as an adsorbent for the successful removal of Reactive Black 5 (RB5) dye from aqueous environments. Materials and methods: The effect of various operating parameters such as pH of solution, dye concentration, contact time, adsorbent dosage, and the temperature was investigated. Results: Maximum adsorption capacity of ...

Effect of citric acid chelating agent on morphology of ZnO particles prepared by hydrothermal method

Abstract Zinc oxide is one of the most widely used and important materials in today's science and industry. In this study, ZnO nanoparticles were synthesized by hydrothermal method. Zinc acetate, citric acid and deionized water was respectively used as a source of zinc ion, solvent and chelating agent. In this study, the effect of citric acid concentration as an additive was studied on morphol...

an investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...

Durable Self-Cleaning Coatings for Architectural Surfaces by Incorporation of TiO2 Nano-Particles into Hydroxyapatite Films

To prevent soiling of marble exposed outdoors, the use of TiO₂ nano-particles has been proposed in the literature by two main routes, both raising durability issues: (i) direct application to marble surface, with the risk of particle leaching by rainfall; (ii) particle incorporation into inorganic or organic coatings, with the risk of organic coating degradation catalyzed by TiO₂ photoactivity....
