METHOD OF VOLT-AMPEROMETRIC ANALYSIS Russian patent published in 1998 - IPC

FIELD: electrochemical analysis, design of hardware and software to control composition and properties of substances in various fields of science, technology and ecology. SUBSTANCE: proposed method of volt-amperometric analysis consists in obtainment of volt-ampere dependence of boundary of separation of working electrode - solution during forward and backward direction of cyclic sweep of polarizing voltage and subsequent differentiation of obtained dependence on voltage. Salient feature of method lies in equipotential summation of currents generated by forward and backward changes of polarizing voltage before differentiation. EFFECT: exclusion of hindering capacitive component from volt-amperogram, increased accuracy, detection limit, resolving power, rate of sweep and informativity of method. 2 dwg
