Spectrophotometric determination of ascorbic acid with iron(III) and p-carboxyphenylfluorone in a cationic surfactant micellar medium.

A simple and highly sensitive spectrophotometric method for the determination of ascorbic acid (AA) was established by using iron(III) and p-carboxyphenylfluorone (PCPF) in a cationic surfactant micellar medium. The apparent molar absorptivity of the proposed method, which does not require an extraction procedure, was 2.05 x 10(6) dm3 mol-1 cm-1 at 655 nm. Beer's law was obeyed in the concentra...

Spectrophotometric determination of molybdenum using surfactant-mediated liquid–liquid extraction

A new spectrophotometric method has been developed for determination of molybdenum using surfactantmediated liquid–liquid extraction. Molybdenum(V) obtained by ascorbic acid reduction in 2.5 M H2SO4 reacted spontaneously with thiocyanate and cetyl trimethyl ammonium bromide (CTAB), forming an intense orange yellow complex that was extracted quantitatively into 1,2-dichloroethane and absorbed at...

Potentiometric Determination of Cationic Surfactant using ‘Polymeric- Inorganic’ Nanocomposite Sensor

A cationic surfactant-selective electrode for sensitive analysis of cationic surfactant has been developed by using a plasticized poly (vinyl chloride) membrane based on nanocomposite cation exchanger polypyrrole zirconium titanium phosphate. The electrode is excellently selective for the cetyl trimethyl ammonium bromide (CTAB) ion over inorganic ions and other cationic surfactants. The membran...

Spontaneous aggregate transition in mixtures of a cationic gemini surfactant with a double-chain cationic surfactant.

Controllable aggregate transitions were realized by mixing two kinds of cationic surfactants, hexylene-1,6-bis(dodecyldimethylammonium bromide) (C(12)C(6)C(12)Br(2)) and didodecyldimethylammonium bromide (DDAB). It was found that two parameters are the main factors determining the aggregation behavior of the mixed system, the total concentration of DDAB and C(12)C(6)C(12)Br(2) (C(T)), and the m...

Complexation of DNA with Cationic Surfactant

Transfection of an anionic polynucleotide through a negatively charged membrane is an important problem in genetic engineering. The direct association of cationic surfactant to DNA decreases the effective negative charge of the nucleic acid, allowing the DNA-surfactant complex to approach a negatively charged membrane. The paper develops a theory for solutions composed of polyelectrolyte, salt,...
