Micellar-Improved Synthesis of bis-Quaternary Ammonium Salts by the Epichlorohydrin Route
(Springer Heidelberg, 2003-12)
A convenient procedure for the synthesis of bis-quaternary ammonium salts from long-chain alkyldimethylamines and epichlorohydrin is studied. An improved preparation of bis-quaternary ammonium salts from N,N-dimethyloctylamine, ...
A novel micellar medium using triblock copolymer for cobalt determination

Flow-injection spectrophotometric determination of novalgin in phrmaceuticals using micellar medium
(Japan Soc Analytical Chemistry, 2007-12-01)
A sensitive flow-injection (FI) procedure with spectrophotometric detection in a micellar medium is proposed for the determination of novalgin. The method is based on the instantaneous formation of a red-orange product ...

Spectrophotometric determination of paracetamol in pharmaceuticals using microwave-assisted hydrolysis and a micellar medium
(2011-12-02)
A new spectrophotometric method employing a micellar medium is proposed for the determination of paracetamol in pharmaceuticals. The method is based on the acid hydrolysis of paracetamol to p-aminophenol (PAP), which under ...

Determination of low-aliphatic aldehydes indoors by micellar electrokinetic chromatography using sample dissolution manipulation for signal enhancement
(Wiley-Blackwell, 2003-02-01)
This work describes a novel approach for the analysis of selected aldehydes (formaldehyde, acetaldehyde, propionaldehyde, and acrolein) and acetone in environmental samples using micellar electrokinetic chromatography ...
Influence of pH and micellar systems on the sensitized photo-oxidation of bovine serum albumin
(John Wiley & Sons Ltd, 2019-02)
Photosensitized oxidation of bovine serum albumin (BSA), by using perinaphtenone as a sensitizer, has been studied at pH 7.4 and 11. The selected sensitizer does not present ground-state complexation with BSA and ensures ...
