    Amperometric sensor for detection of chloride ions.

  • Original language description

    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 uM, 100 uM and 10 uM for solid AgNO3, solution of AgNO3 and/or solid silver particles, respectively. The CPE modified with silver particles is the most sensitive to thepresence 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.

    Amperometrický sensor pro detekci chloridových iontů

  • Czech description

    Chloridové ionty hrají významnou roli v klinické diagnostice, monitorování životního prostředí a průmyslových aplikací. Měřili jsme chloridové ionty na uhlíkové pastové elektrodě (CPE) a modifikované pastové uhlíkové elektrodě pomocí AgNO3 a nebo rovněžpevné kovové částice stříbra. Detekční limit jsme stanovily byl 100 uM pro CPE a 10 uM pro modifikovanou elektrodu. Poté jsme modifikaci elektrody využili na miniaturizovaný elektrochemický systém s mikropotenciostatem a tištěnými elektrodami.
