Title
(EN) CHEMICAL OXYGEN DEMAND SENSING USING PSEUDO-GRAPHITE
(FR) DÉTECTION DE DEMANDE CHIMIQUE EN OXYGÈNE À L'AIDE DE PSEUDO-GRAPHITE
Abstract
(EN)
Methods, electrodes, and sensors for pH sensing using pseudo-graphite are disclosed. In one illustrative embodiment, a method may include coating a pseudo-graphite material onto a surface of an electrode substrate to produce a pseudo-graphite surface. The method may also include exposing the pseudo-graphite surface to a sample to detect organic content in the sample.
(FR)
L'invention concerne des procédés, des électrodes et des capteurs pour la détection de pH à l'aide de pseudo-graphite. Selon un mode de réalisation donné à titre d'exemple, un procédé peut comprendre le revêtement d'un matériau de pseudo-graphite sur une surface d'un substrat d'électrode pour produire une surface de pseudo-graphite. Le procédé peut également comprendre l'exposition de la surface de pseudo-graphite à un échantillon pour détecter un contenu organique dans l'échantillon.
