Abstract
Los dispositivos de medición se pueden usar para identificar la concentración de especies de arsénico en muestras de agua. Los dispositivos de medición pueden tomar la forma de tiras reactivas que incluyen un sustrato con por lo menos una región de prueba que incluye una cantidad de un medio de prueba. El reactivo de plata incluye una estructura de polímero y un componente de plata que es estabilizado por la estructura, pero sigue siendo lo suficientemente reactivo para funcionar como un sensor colorimétrico de arsénico, por ejemplo, ((Ag(H2btc))(Ag2(Hbtc)))n. El medio de prueba al principio sustancialmente incoloro exhibe una respuesta de cambio de color cuando se expone a especies de arsénico, por ejemplo, arsina, generada de muestras que incluyen tan solo 5 ppb de arsénico, con un color cada vez más oscuro a medida que aumenta la concentración de arsénico. Las tiras de prueba fabricadas con el polímero de coordinación de plata muestran una sólida estabilidad frente a la luz y agua, lo que permite una alternativa a los kits de prueba de campo a base de mercurio en pruebas de campo del mundo real bajo luz solar directa y condiciones de alta humedad.
