Equilibrium and Kinetic Studies on Adsorption of Methylene Blue Dye by ZnO Nanoparticles Synthesized by Hydrothermal Method
Metal oxides play significant role in many fields of nanotechnology including nanocatalysis, sensing, supermagnetic properties, fuel cells, nanoenergy storage and conservation. Dyes are synthetic compounds which have wide range of application in textiles, paints etc., and the dye effluents from the dyeing industries cause water pollution. In this present study, ZnO photocatalyst have been synth...
متن کاملAdsorption of Methylene Blue in Aqueous Phase by Fly Ash, Clay and Walnut Shell as Adsorbents
Methylene Blue (MB) adsorption from aqueous phase was investigated using three types of adsorbents. Granular solid adsorbents were prepared from waste wood fly ash and clay. Experiments were conducted in a batch system for determining sorption equilibria. For continuous process, the adsorbents were packed in a column to remove MB from the synthetic wastewater. The fabricated adsorbents and also...
متن کاملAdsorption Equilibrium, kinetics and thermodynamics of methylene blue from aqueous solutions using biopolymer oak sawdust composite
Oak sawdust (OSD), furniture industrial waste was chemically treated with 0.1N NaOH to give hydrolyzed oak sawdust (HOSD) which was immobilized on alginate biopolymer. Hydrolyzed oak sawdust composite (HOSDC) was utilized as low-cost adsorbent to remove basic dye (methylene blue, MB) from aqueous solution. HOSD and HOSDC were characterized by using Scanning electron microscope (SEM), thermo gra...
متن کاملAdsorption of Methylene Blue from Aqueous Solutions by Silk Cocoon
This study concerns the performance of cocoons spun by silk worms as a natural adsorbent for removal of Methylene Blue (MB) from aqueous solutions. To study the adsorption process, the effect of various parameters such as contact time, adsorbent dosage, dye initial concentration, and pH of the solution were investigated. According to the experiments, the kinetic data were best described by ...
متن کاملAdsorption and Desorption Mechanisms of Methylene Blue Removal with Iron-Oxide Coated Porous Ceramic Filter
Adsorption and desorption mechanisms of methylene blue (MB) removal with iron-oxide coated porous ceramics filter (IOCPCF) were investigated in batch and column mode. The results revealed that MB removal mechanisms included physical adsorption and chemical adsorption, of which chemical adsorption by surface ligand complex reaction played a dominant role after infrared spectrum analysis. Recycli...
