Mesoporous Carbon Modified with Iron Oxide Based Magnetic Nanomaterials for Removal of Malachite Green Dye From Aqueous Solution
Mesoporous carbon (CMK-3) modified with Fe3O4 nanoparticles has been successfully synthesized and characterized by powder X-ray diffraction (XRD), N2 adsorption-desorption, scanning electron microscope (SEM) and transmission electron microscopy (TEM).The results depict that the synthesized Fe-CMK-3 preserved the ordered mesoporous structure of CMK-3, and magnetic species were dispersed insi...
full textRemoval of Malachite Green from Aqueous Solution by Zeolite- Iron Oxide Magnetic Nanocomposite
Discharge of dye effluents into the natural streams may be toxic to the aquatic lives as well as human being. In the present studies, zeolite was synthesized from coal fly ash by alkaline hydrothermal treatment and mixed with magnetite nanoparticles in suspension to produce zeolite-iron oxide magnetic nanocomposite. It was used as adsorbent for the removal of malachite green dye from aqueous so...
full textRemoval of Malachite Green dye from aqueous solution using MnFe2O4/Al2O3 Nanophotocatalyst by UV/H2O2 process
Background & Aims of the Study: Malachite Green (MG) is the most commonly used substance for dying cotton, food & pharmacy industries, paper, leather and silk. On inhalation it can cause difficult breathing, while on the direct contact it may cause permanent injury of the eyes of human and animals, burning sensations, nausea, vomiting, profuse sweating, mental confusion and met...
full textModified Nanoporous Carbon Material for Anionic Dye Removal from Aqueous Solution
In this study, the adsorption behavior of anionic dyes from aqueous solution onto mesoporous carbon material (CMK-1) and modified with polymer (PANI/CMK-1) has been investigated as a function of parameters such as adsorbent dose (0.08-0.8 g/L), solution pH 3–10, contact time and initial concentration (10-100 mg/L). The influence of these parameters on the adsorption capacity has been studied us...
full textRemoval of Malachite Green Dye from aqueous solution by Fenton Oxidation
In order to see the influence of different variable parameters (initial pH of the solution, Fe++ concentration and H2O2 concentration) and the efficiency to remove Malachite Green dye (Basic Green 4) from aqueous solution, Fenton Oxidation method was employed. Then different parameters were studied using known concentration (150 mg/l) and initial COD (256 mg/l) of prepared dye synthetic solutio...
full textElectrochemical Treatment Of Malachite Green Dye Solution Using Iron Electrode
Present study was performed to investigate the variables that influence the removal efficiency of malachite green (aniline) dye from aqueous solution by an electrochemical (EC) technique. The batch EC studies were performed using iron electrode to evaluate the effect of operating parameters such as pHo and processes parameters such as current density and initial dye concentration. Parameters pH...
