氯金酸修饰对再生电极检测性能的影响
Influence of Chloroauric Acid Modification on Detection Performance of Regenerated Electrode
摘要
Abstract
In order to explore the influences of chloroauric acid on detection performances of regenerated electrode, firstly, the conditions of regeneration and chloroauric acid modification for electrode were optimized. Then analyzed and evaluated before and after the gold chloride acid modified electrode regeneration detection performance. The results showed that, under the optimized regeneration conditions (0.1 mol/L citric acid-sodium citrate, pH 2.4, 30 min regeneration time), the current of regenerated electrode could recover to about 85％of its original current. Under the optimized conditions of chloroauric acid modification (308.89μg、90 min), the current of regenerated electrode increased nearly 60％. In addition, the detection limit of regenerated electrode for Listeria monocytogenes was from initial 3.08 × 103 cfu/mL reduced to 2.1 × 102 cfu/mL, increasing 14.6 times after modification by chloroauric acid. The stability has also improved nearly 10％. The research results showed that the disposable electrode has the ability to reuse after regeneration and modification by chloroauric acid.关键词
