The removal of Victoria blue dye form water and waste water by adsorption on China clay is greatly influenced by the pH of the medium. The pH of the adsorbate solution effect the nature of the surface properties of adsorbents the degree of ionization and speciation of aqueous adsorbate species and ultimately the rate and extent of the adsorption. The initial concentration of the dye taken was 1...

The adsorbents of starch grafted p-tert-butyl-calix[4,6,8]arene-SGCn (SGC4, SGC6, SGC8) are prepared. The products are characterized by FTIR, elemental analysis, thermal gravimetric analysis and scanning electron microscope. Static adsorption behavior is studied by using SGC8 as adsorbent, butyl Rhodamine B (BRB) solution as simulation dye wastewater. The adsorption of BRB onto SGC8 fits the se...

The use of low-cost, locally available, highly efficiencient and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. This study investigates the potential use of activated carbon prepared from the Annona squmosa seed for the removal of methyl red (MR) dye from simulated wastewater. The effects of different syst...

In this research miswak leaves, agriculture wastes, available in large quantity in Saudi Arabia, was used as low-cost adsorbent for removing methylene blue (MB) dye. Equilibrium behavior of miswak leaves was investigated by performing batch adsorption experiments. The effects of [MB] 0, pH, contact time and adsorbent dose were evaluated. An alkaline pH (10.6) was favorable to the adsorption of ...

Of 18 commercially used textile dyes, eight were degraded by the white rot fungus,Phanerochaete chrysosporium, by 40 to 73% based on decrease of colour. Both the lignin-degrading enzyme system ofP. chrysosporium and adsorption to its cell mass were involved in the degradation of the diazo dye, Reactofix Gold Yellow. Degradation was best achieved by adding the dye to the medium and then inoculat...

Photoelectrodes for dye-sensitized solar cells were fabricated using commercially available zinc oxide (ZnO) nanoparticles and sensitized with the dye N719. This study systematically investigates the effects of two fabrication factors: the ZnO film thickness and the dye adsorption time. Results show that these two fabrication factors must be optimized simultaneously to obtain efficient ZnO/N719...

introduction: dye removal from industrial wastewater has been considered as one of the most environmental issues. recently, new methods of treatment such as catalytic ozonation have been used to increase dye removal efficiency. so, the efficiency of catalytic ozonation by copper coated zeolite as a catalyst in the removal of reactive red 198 was investigated. materials & methods: in order to re...

Textile industries discharge a large quantity of colored wastewater which is harmful to the ecosystem. In this study, two kinds of dyes were investigated: the mono azo Acid Orange 7 (AO7) and diazo Reactive Green 19 (RG19). The photocatalytic degradation of single (AO7, RG19) azo dye and binary (AO7 and RG19 mixture) azo dye aqueous solutions was photocatalyzed by commercial titanium dioxide (T...

  Background & Aims of the Study: Dyes are one of the most hazardous materials in various industries which can problems in health human, environment and ecosystem. The purpose of this study is the removal of Acid Orange 25 (AO25) diazo dye in aqueous solutions by adsorption onto clinoptilolite (CP) zeolite: study kinetic and isotherm model: experimental design and optimization. ...

Ginger waste material (GWM) has been utilized as adsorbent for removal of hazardousPatent Blue VF (PBVF) dye from aqueous solution. Batch adsorption experiments wereperformed as a function of pH, contact time, dye concentration, adsorbent dose and temperature.The optimum pH required for the maximum adsorption was found to be 2. The experimentalequilibrium adsorption data were tested using Langm...
