Abstract

Determination Of Cephalosporines In Presence Of Tungsten (VI) With The Help Of Polarographic Catalytic Waves

Author(s): K Swarna Rani, V Suryanarayana Rao, N Ch. Varadacharyulu

A rapid and sensitive method for the polarographic determination of cephalosporins is described. In presence of tungsten (VI), Cefachlor exhibited a catalytic peak at -2.3 V vs SCE in 0.9 M H2SO4 medium. Optimum conditions are established for the method developed. This analytical method is useful for determining the drug as well as the metal. The method is applied to clinical samples containing these compounds.
