摘要：
New polymeric sensors based on bidentate neutral organophosphorus compounds of varied structure with addition of chlorinated cobalt dicarbollide, which are highly sensitive to Fe3+, Y3+, La3+, Pr3+, Nd3+, and Eu3+, cations in a wide range of concentrations at pH 2, were suggested. The selectivity, detection limits, and pH-dependence of the potential of the sensors developed were studied. The influence of chlorinated cobalt dicarbollide on the electrochemical characteristics of the sensors was demonstrated.
