摘要: Abstract It was found that the copolymer poly(aniline- co - o -aminophenol) (PANOA) can strongly catalyze reduction of arsenate in a NaCl solution, which proved by cyclic voltammetry and determination activation energy. On basis electrocatalytic arsenate, PANOA used as probe to determine directly arsenate. The activity electrode toward As(V) depended on pH applied potential. Under optimal conditions, be concentration wide linear range ( n = 19) 0.949 495 μM with correlation coefficient 0.995 limit detection 0.495 μM. sensitivity 0.192 μA μM −1 cm −2 . had good storage stability less negative operation potential −0.15 V (vs. SCE).
