EFEITO DE SURFACTANTES NA ESTABILIDADE DE COMPOSTOS DE USO TERAPEUTICO
(1990-12-01)
A critical revision of literature as regards to the drug stability in the presence of surfactants were realized. The functional groups envolved in the drug decomposition were used to the development of the discussion. The ...

Spectrophotometric flow-injection determination of sulphite in white wines involving gas diffusion through a concentric tubular membrane
(2003-07-14)
A flow-injection system is proposed for the spectrophotometric determination of sulphite in white wines. The method involves analyte conversion to SO2, gas diffusion through a Teflon® semi-permeable membrane, collection ...

High viscosities of cationic and anionic micellar solutions in the presence of added salts
(1986)
Viscosities of micelles of cetyltrimethylammonium salts (CTAX, X = tosylate (TOS-), Cl-, Br-, NO3 -) in the presence of Cl-, Br-, NO3 -, benzene sulfonate (BS-), and TOS-, of cetylpyridinium chloride (CpyC) in the presence ...
