Oscillopolarographic titration — a promising volumetric method …
1982年2月1日 · An oscillopolarographic titration is a volumetric method using the incision on an a.c. oscillopolarogram (dE/dt = f(E) curve) of the titrant, titrate or indicator to locate the end-point of titration.
Oscillographic polarography is at present used in organic, bio-organic1, analytical, and physical chemistry, pharmacology and medicine, clinical studies and therapy, geochemistry, oceanography, and botany.

2011年4月30日 · This paper reviews the development of exchange oscillopolarographic titration research, and focuses on its change in the past 20 years. At different temperatures, indicators, pH, and other situations, exchange oscillopolarographic titration was used to detect phosphorus, silver, lead, thallium, cobalt, nickel, potassium bromate, potassium ...
OSCILLOPOLAROGRAPHIC TITRATIONS
Review on oscillopolarographic titrations has shown that this branch of titrimetric analysishas out-standing advantages over the other physico-ehemical volumetric methods in manyaspects, such as very simple manipulation and instrumentation, visual end-point detection,rapid analytical procedures and wide applications.
Oscillopolarographic detection and determination of polyanions: …
Oscillopolarographic determinations were carried out on the Polaroskop P-576 Krizik fitted with a droppingmercury electrode. The first curve was registered on a universal oscillopolarograph constructed by Sevcik and VIetzl (6).
A simple oscillopolarographic technique for recognition and …
Oscillopolarographic and spectrophotometric measurements were carried out at room temperature at the concentration of 32/~g DNA per ml in 0.3 M ammonium formate with o.o5 M sodium phosphate (pH 7). The absorbancy at 260 m# or the depth of the cathodic indentation of denatured DNA was expressed as lOO%. i, spectrophotometry at 26o m#; 2 ...
