Optimization of Orange G dye adsorption by activated carbon of Thespesia populnea pods using response surface methodology.

M Arulkumar et al.

Journal of hazardous materials, 186(1), 827-834 (2011-01-15)

Thespesia populnea is a large tree found in the tropical regions and coastal forests of India. Its pods were used as a raw material for the preparation of activated carbon. The prepared activated carbon was used for the adsorptive removal

Biosorption of an Azo Dye by Aspergillus niger and Trichoderma sp. Fungal Biomasses.

Arumugam Sivasamy et al.

Current microbiology, 62(2), 351-357 (2010-07-21)

Biosorption is an eco-friendly and cost-effective method for treating the dye house effluents. Aspergillus niger and Trichoderma sp. were cultivated in bulk and biomasses used as biosorbents for the biosorption of an azo dye Orange G. Batch biosorption studies were

Decolourization of the azo dye Orange G in aqueous solution via a heterogeneous Fenton-like reaction catalysed by goethite.

Honghai Wu et al.

Environmental technology, 33(13-15), 1545-1552 (2012-09-20)

Decolourization of the azo dye Orange G (OG) was investigated by using goethite/H2O2 as a heterogeneous Fenton-like reagent. Five principle operational parameters, namely pH, ion strength, concentrations ofgoethite (alpha-FeOOH) and hydrogen peroxide (H2O2), and reaction temperature, were taken into account

Photocatalytic degradation of three azo dyes using immobilized TiO2 nanoparticles on glass plates activated by UV light irradiation: influence of dye molecular structure.

A R Khataee et al.

Journal of hazardous materials, 168(1), 451-457 (2009-03-13)

In order to discuss the effect of chemical structure on photocatalysis efficiency, the photocatalytic degradation of three commercial textile dyes (C.I. Acid Orange 10 (AO10), C.I. Acid Orange 12 (AO12) and C.I. Acid Orange 8 (AO8)) with different structure and
