Abstract

La presente se refiere a métodos y composiciones para identificar la presencia de tensioactivos en agua. La presente es bastante superior al arte previo porque puede formar un complejo coloreado en la mitad del tiempo, puede evitar la necesidad de difíciles etapas de separación, puede usar un solvente más seguro y evitar la formación de espuma sucia. Incluye la adición al agua de un reactivo de tiocianato de cobalto, previamente preparado a partir de una sal de cobalto y una sal de tiocianato, que forma un complejo coloreado con el tensioactivo. Luego se añade cloroformo al agua. El reactivo de cobalto provoca que virtualmente todo el tensioactivo forme un complejo coloreado que rápidamente migra al cloroformo y evita el espumado del tensioactivo. Una vez en el cloroformo, un espectrómetro UV-vis puede identificar fácil y precisamente el tipo y la cantidad de tensioactivo que estaba en el agua.
