Abstract

"MéTODO, COMPOSIçãO E DISPOSITIVO PARA A DETERMINAçãO DE HALOGêNIOS LIVRES EM FLUIDOS AQUOSOS" Um sensível e conveniente método, composição de reagente e dispositivo de testagem unificados é apresentado para a determinação de halogênios livres em amostras de fluidos aquosos a serem testados. A composição reagente basicamente consiste de um material indicador do tipo azina e uma quantidade eficiente de um material catalisador do tipo benzidina, a mistura dos dois materiais preferivelmente sendo impregnada em um material da matriz para facilitar o manuseio e a utilização.
