Photocatalytic Removal of Malachite Green Dye from Aqueous Solutions Using Halloysite–TiO2 Nanocomposite

Adsorption of Malachite Green Dye from Aqueous Solutions Using Roots of Azolla Filiculoides

Pollution of water resources by various pollutants is nowadays a global environmental issue. Among the different type of water pollutants, dye represents a major polluting group. In this study, Azolla filiculides roots have been used for adsorption of Malachite Green (MG), a cationic dyed from aqueous solution. In this study, effects of operating parameters such as initial concentration of dye ...

Removal 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...

Photocatalytic Removal of Acid Blue 113 Dye from Aqueous Solutions Using Zinc Oxide-Kaolin Nanocomposite under Visible Light Irradiation

Background and purpose: Textile industries produce huge amounts of colored wastewater. Synthetic dyes cause serious problems to human health and aquatic organisms due to their toxic and carcinogenic properties. In this study, Acid Blue 113 (AB113), which is stable and persistent against conventional treatment methods was selected as the target contaminant. Materials and methods: The synthesis ...

Removal of bromocresol green from aqueous solutions using chitin nanofibers

Modeling of Malachite Green Removal from Aqueous Solutions by Nanoscale Zerovalent Zinc Using Artificial Neural Network

The commercially available nanoscale zerovalent zinc (nZVZ) was used as an adsorbent for the removal of malachite green (MG) from aqueous solutions. This material was characterized by X-ray diffraction and X-ray photoelectron spectroscopy. The advanced experimental design tools were adopted to study the effect of process parameters (viz. initial pH, temperature, contact time and initial concent...

Removal 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...
