Polarography, especially alternating current polarographic techniques
and other voltametric techniques, play at present a proeminent part in
the quantitative determination of some organic compounds of biologica
l and pharmaceutical significance, In this respect, sulfur-containing
compounds on the type of cephalosporins, compounds with antibiotica ac
tion like penicilines, are easy reduced on the dropping mercury electr
ode, in conditions of reversibility controlled by diffusion, which ass
ure the obtaining of clearly defined and intense enough signals, which
will permitted the quantitative determination of these compounds, in
the concentration range 10(-3)-10(-7) mol 1, from biological media. Th
e precision of the elaborated method is very good with a relative stan
dard deviation of 1.5% for a concentration of 0.5 mug/nil, of the stud
ied cephalosporin.
