Benzylpenicillin-selective electrode and its analytical applica­tion
Benzylpenicillin-selective electrode based on a neutral carrier - p-trifluoroacetylbenzoic heptyl ether, has been devel­oped. The influence of plasticizer nature on the selectivity to benzylpenicillin has been investigated and optimal membrane composition has been found. Technique for benzylpenicillin determination in drugs was proposed.
