Abstract

PROCESSO PARA DETERMINAçãO DA CONCENTRAçãO DE ANALITO EM UMA PILHA ELETROQUìMICA. Processo para determinação da concentração de um modelo oxidado ou reduzido de uma amostra redox em um célula eletroquímica do tipo compreendendo um elétrodo de atuação e um contra-elétrodo espaçado do eletrodo de atuação de forma que os produtos da reação a partir do contra-elétrodo cheguem ao elétrodo de atuação, o processo compreendendo as etapas de aplicação (21) de um potencial elétrico entre os elétrodos, de forma que a oxidação de elétrodo da amostra redox é controlada por difusão, determinando a corrente como uma função de tempo, estimando a magnitude da corrente de estado estacionário (23), invertendo o potencial, e novamente determinando a corrente como a função do tempo e estimando o estado estacionário do potencial inverso (25).
