Electrochemical Behavior of Hydroquinone and Catechol at a Silsesquioxane‐Modified Carbon Paste Electrode
نویسندگان
چکیده
Um eletrodo de pasta de carbono modificado com o polímero cloreto de 3-n-propil-4-picolina silsesquioxano foi testado como sensor para isômeros do di-hidroxibenzeno. O sensor apresentou desempenho excelente para a determinação eletroanalítica simultânea de hidroquinona e catecol. As curvas de calibração obtidas foram lineares na faixa de concentração de 10,0 a 450,0 μmol L para a hidroquinona (r = 0,998) e de 10,0 a 300,0 μmol L para o catecol (r = 0,997). O limite de detecção visual foi de 10,0 μmol L para ambos os isômeros.
