Densitometric determination of conjugated oestrogens in the raw material and in pharmaceutical preparations
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
A densitometric method for determination of complex mixtures of conjugated oestrogens in raw material and tablets was developed. The proposed procedure comprised hydrolysis of sodium sulphate esters of oestrone, equilin, ...
Potentiometric investigation of the stability of palladium(II) complex of pralidoxime chloride in aqueous solution
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
The formation of a complex between palladium(II) chloride and pralidoxime chloride (PAM-2Cl) has been studied by means of potentiometric pH measurements. The real stability constant of the complex in aqueous medium of ionic ...
Spectrophotometric investigation of complex formation of an oxime PAM-4Cl with palladium(II) and its analytical application
(Journal of Pharmaceutical and Biomedical Analysis, 1990)
The colour reaction of 4-hydroxyiminomethyl-1-methylpyridinium chloride (PAM-4Cl) and palladium(II) chloride has been investigated. The optimum reaction conditions, spectral characteristics, conditional stability constant ...
