General description

Orange G (C.l. 16230) is the disodium salt of benzeneazo-2-naphthol-6,8-disulfonic acid, C₁₆H₁₀N₂O₇S₂Na₂. Orange G, also known as wool orange 2G, is a component in several industry applications including cytology, histology, biology, and industrial staining. It is a component of Mallory′s connective tissue stain.

Application

Certified for use in Mallory′s connective tissue stain; Wilson-Ezrin method for pituitary acidophils; Kreyberg′s method for keratin and mucus; as a counterstain following Heidenhain′s iron hematoxylin on paraffin sections; Flemming′s triple stain on paraffin sections of onion root.

Orange G is typically used as a background or cytoplasmic stain for various biological samples including a common application within clincial cytology within Papanicolaou varients.

Complete degradation of Orange G by electrolysis in sub-critical water.

Asli Yuksel et al.

Journal of hazardous materials, 190(1-3), 1058-1062 (2011-03-29)

Complete degradation of azo dye Orange G was studied using a 500 mL continuous flow reactor made of SUS 316 stainless steel. In this system, a titanium reactor wall acted as a cathode and a titanium plate-type electrode was used

Mechanism of adsorption of anionic dye from aqueous solutions onto organobentonite.

Jianfeng Ma et al.

Journal of hazardous materials, 186(2-3), 1758-1765 (2011-01-14)

Organobentonite is suggested as potential super-sorbents for the removal of dyes from wastewater. All kinds of organobentonites are synthesized to adsorb dyes; however, the mechanism of the adsorption is still unclear. In this paper, organobentonites were first modified with hexadecyltrimethylammonium

Suneet Khandelwal et al.

International journal of oral science, 2(1), 45-52 (2010-08-10)

To analyse the cytomorphological features of keratinocytes in smears obtained from the oral mucosa of tobacco users and from oral squamous cell carcinoma lesions. Oral smears were obtained from clinically, normal appearing mucosa of oral squamous cell carcinoma patients (n=20)

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
