Removal of crystal violet from water by magnetically modified activated carbon and nanomagnetic iron oxide
Magnetically modified activated carbon, which synthesized by nanomagnetic iron oxide, was used for fast and effective removal of Crystal Violet from aqueous solutions. The scanning electron microscopy (SEM) images of nano-adsorbent showed that the average sizes of adsorbent are less than 100 nm. The various parameters, affecting on adsorption process, were examined including pH and temperature ...
متن کاملArsenic removal by iron-modified activated carbon.
Iron-impregnated activated carbons have been found to be very effective in arsenic removal. Oxyanionic arsenic species such as arsenate and arsenite adsorb at the iron oxyhydroxide surface by forming complexes with the surface sites. Our goal has been to load as much iron within the carbon pores as possible while also rendering as much of the iron to be available for sorbing arsenic. Surface ox...
متن کاملRemoval of crystal violet from aquatic environment by surfactant-modified dolomite
This paper presents the adsorption of crystal violet (CV+) from aqueous solution on surfactant-modified dolomite. Liquid phase batch operations were carried out to observe the effect of various experimental parameters such as initial dye concentration, adsorbent dosage, pH and NaCl concentration. The optimum conditions for these parameters were calculated by Taguchi method. Equilibrium isotherm...
متن کاملDegradation of crystal violet using copper modified iron oxide as heterogeneous photo-fenton reagent
The heterogeneous photo-Fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. The photocatalyst has been prepared by coprecipitation method. The rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. It has been observed thatphotocatalytic degradation follows pseudo first order kinetics. The effect of various param...
متن کاملNitrate Removal from Aqueous Solutions Using Granular Activated Carbon Modified with Iron Nanoparticles (RESEARCH NOTE)
Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...
