Calcium oxide was used as photocatalyst for the degradation of indigo carmine dye solution in the visible, long UV, and short UV radiation. We have investigated the effectiveness of degradation of indigo carmine dye solution at pH 9 and 12 using calcium oxide with the particle size of 30–36 nm by varying the concentration, dose of adsorbent, and duration. It has been found that the degradation of indigo carmine dye is effective at pH = 9, when 0.12 g of calcium oxide was used. The nature of… 
Photocatalytic degradation of indigo carmine dye using Nd2O3 coated Tio2 materials
Nd2O3 coated TiO2 material was synthesized by hydrothermal technique at relatively low P-T conditions. Micro and macrostructure of the material is being carried out by SEM and XRD. Photocatalytic
Removal of COD and color of Carmine Dye by Photocat alytic Ozonation with effect of Zinc Oxide catalyst
Photocatalytic ozonation is found to be one of the most effective ways to degrade dye waste water. Pho tocatalytic ozonation facilitates ozone decomposition and hydro xyl radical formation. For this
TiO2/activated carbon derived from waste coffee grounds (TiO2/WCGAC) has been prepared by a sol gel method . Waste coffee ground was chemically activated using hydrochloric acid 0.1 M solution and
An Efficient Approach Towards the Photodegradation of Indigo Carmine by Introducing ZnO/CuO/Si Ternary Nanocomposite as Photocatalyst
The authors report a facile route for the large scale synthesis of CuO/ZnO/Si ternary system achieved by non-equilibrium synthesis using High Energy Ball Milling (HEBM) technique. The synthesized
Electrocoagulation of the indigo carmine dye using electrodes produced from the compression of metallurgical filing wastes
Indigo carmine (IC) is a dye that is widely used in textile industries. Since the dyes lixiviation reaches about 30%, these compounds are largely discharged in effluents, thus contaminating rivers
Evaluation of La-Doped CaO Derived from Cockle Shells for Photodegradation of POME
Photocatalysis has merged to be one of the most promising technology in wastewater remediation. However, the application of photocatalysis in treating palm oil mill effluent (POME) is still limited.


Photodegradation of Rhodamine B in Presence of CaO and NiO-CaO Catalysts
A CaO catalyst was prepared by mild calcination (650°C) of facilely precipitated Ca(OH)2 and compared to an NiO-CaO catalyst obtained from an Ni(OH)2/Ca(OH)2 coprecipitate as a precursor. Both
Carbon-Doped Titanium Dioxide : Visible Light Photocatalysis and EPR Investigation
X-band EPR studies of a series of undoped and carbon-doped titania powders reveal the presence of a carbon-centered radical species. The concentration of spins is five to six orders of magnitude
Structural characterization and photocatalytic properties of novel Bi2FeVO7
Bi2FeVO7 was prepared by a solid-state reaction technique for the first time and the structural and photocatalytic properties of Bi2FeVO7 were studied. The results shows that this compound
A review of electrochemical treatments for colour elimination
The application of electrochemical techniques as a tertiary treatment to eliminate colour from textile effluents has increased rapidly in the last few years. In general, the dyes are decomposed by
