Flow-injection determination of nickel with voltammetric detection by the catalytic hydrogen current

Abstract

It is shown that the analytical signal in a flow-injection system with voltammetric detection can, in principle, be measured by the catalytic current of hydrogen liberation in solutions of nickel(II) cysteinates in the range 0.3-6.0 μg/mL Ni with a throughput capacity of 25 samples/h. © 1996 MAEe Cyrillic sign;K Hayκa/Interperiodica Publishing.
