Sonovoltammetric Determination of 4-Nitrophenol on Diamond Electrodes
نویسندگان
چکیده
A determinação sonovoltamétrica do 4-nitrofenol foi estudada sobre um eletrodo de diamante dopado com boro. Foram observadas melhorias significativas na sensibilidade analítica devido à limpeza da superfície eletródica e ao aumento no transporte de espécies ao eletrodo proporcionados pelo ultra-som. Desta maneira, para os processos de oxidação e redução, os limites de detecção diminuíram de 11.7 para 3.87 e de 6.38 para 2.57 μg L-1, respectivamente.

In order to investigate nitro-substitutent's effect on degradation of phenols at boron-doped diamond (BDD) anodes, cyclic voltammetries of three nitrophenol isomers: 2-nitrophenol (2NP), 3-nitrophenol (3NP) and 4-nitrophenol (4NP) were studied, and their bulk electrolysis results were compared with phenol's (Ph) under alkaline condition. The voltammetric study showed nitrophenols could be attac...
