How it works The average response is then used for subsequent data analysis
Polarography First voltar DIE Differs forr unstirred Current,i ● dropping working el Current va Lifetime of Time
Polarography First voltammetric technique Differs form hydrodynamic ●unstirred (diffusion dominates) ●dropping Hg electrode (DME) is used as a working electrode Current varies as drop grows then falls off
Polarographic data Two typ es of information are obtained diffusion current /2 halfwave potential E 112
In polarographic analysis, supporting electrolyte is usually added to increase the current-conductivity and eliminate migration current. Usually relatively higher concentration of strong electrolytes(alkali metal salts) serves as supporting electrolyte 通常用通入N2,H2等方法消除溶解氧对极谱测定的影 响
