V originále
Chloride ion sensing is important in many fields such as clinical diagnosis, environmental monitoring and industrial applications. We have measured chloride ions at a carbon paste electrode (CPE) and at a CPE modified with solid AgNO3, a solution of AgNO3 and/or solid silver particles. Detection limits (3 S/N) for chloride ions were 100 mu M, 100 mu M and 10 mu M for solid AgNO3, solution of AgNO3 and/or solid silver particles, respectively. The CPE modified with silver particles is the most sensitive to the presence chloride ions. After that we approached to the miniaturization of the whole electrochemical instrument. Measurements were carried out on miniaturized instrument consisting of a potentiostat with dimensions 35 x 166 x 125 mm, screen printed electrodes, a peristaltic pump and a PC with control software. Under the most suitable experimental conditions (Britton-Robinson buffer, pH 1.8 and working electrode potential 550 mV) we estimated the limit of detection (3 S/N) as 500 nM.
In Czech
Stanovení chloridových iontů je důležité v mnoha oborech, jako je např. klinická diagnostika, monitoring životního prostředí a průmyslové aplikace. Měřili jsme chloridové ionty na uhlíkové pastové elektrodě (CPE) a na CPE modifikované pevným AgNO3, roztokem AgNO3 a/nebo stříbrnými částicemi. Detekční limit v optimálních podmínkách byl stanoven jako 500 nM.
