Anaerobic Degradability of Alcohol Ethoxylates and Related Non-Ionic Surfactants

The determination methods for non-ionic surfactants

A large number of non-ionic surfactants are discharged into water, which cause deterioration of water quality. Non-ionic surfactants have become an indicator of water quality monitoring. This article provides an overview of the classification of non-ionic surfactants, introduces the nature and hazards of fatty alcohol ethoxylates and alkyl phenol ethoxylates, and analyzes determination of non-i...

Alcohol Ethoxylates proposed draft factsheet

Bacterial decolorization of acid orange 7 in the presence of ionic and non-ionic surfactants.

The effects of the non-ionic surfactant Triton X-100, the cationic surfactant cetyltri-methylammonium bromide (CTAB) and the anionic surfactant sodium N-lauroyl sarcosinate (SLS) on the decolorization of the reaction medium containing the monoazo dye Acid Orange 7 (AO7) by Alcaligenes faecalis and Rhodococcus erythropolis were studied. It was found that the surfactants influenced in different w...

A three stage model for adsorption of non ionic surfactants

The adsorption of nonionic surfactants onto both hydrophilic and hydrophobic surfaces has been extensively researched from the point of view of physical chemistry.i,2 In these studies nonionic surfactants were assumed to interact with both the surface and each other. The resultant adsorption isotherms were then explained in terms of interaction strength and surfactant orientation. A five stage ...

In vitro evaluation of itraconazole loaded vesicles prepared from non-ionic surfactants

This study aims to investigate the capability of forming itraconazole containing niosomes with Span 60 and Brij 58 as non-ionic surfactants. Lower cost and higher stability makes niosomes a more suitable choice in comparison with liposomes.The capability to form vesicles as an itraconazole delivery system and the influence of different factors such as type of surfactant and molar ratio of chole...
