Voltammetric determination of uric acid by using gold nanotubule electrode
摘要:
Gold nanotubule membranes were prepared by using electroless deposition of gold within the pores and surfaces of polycarbonate track-etched membranes. And the gold nanotubule membrane was used as an electrode for determination of uric acid in urine samples for the first time. In Britton-Robinson buffer of pH 4.56, uric acid exhibited well-defined differential pulse voltammograms. And the interference between coexistent ascorbic acid and uric acid was overcome owing to the attractive ability of the gold nanotubule electrode to yield a large anodic peak difference ca. 0.404 V (vs. SCE). The proposed method was then applied to the determination of uric acid in urine without any pretreatment.
