The invention relates to a cleaning, disinfection and indicator agent, comprising a water-soluble permanganate, in particular, for mixing with an agent, guaranteeing an alkaline medium with a pH value of at least 11 and a further oxidising agent, in addition to the water-soluble permanganate, the oxidation potential of which lies above that for manganese VII to manganese VI, pH-buffer substances, preferably primary and/or secondary alkali carbonates such as sodium carbonate and/or sodium bicarbonate and oxidation- resistant polyphosphates. The invention further relates to methods for cleaning, disinfecting and monitoring the purity of commercial and industrial plants, or plant components and the application of such an agent as indicator solution, for determining the purity of commercial and industrial plants, or plant components, by means of recording the intensity of light emitted by the solution in the violet wavelength range.
L'invention concerne un agent de nettoyage et de désinfection et agent indicateur, comprenant un permanganate hydrosoluble, en particulier pour le mélange avec un agent permettant d'obtenir un milieu alcalin d'un pH au moins égal à 11, et, en plus du permanganate hydrosoluble, un autre agent oxydant, dont le potentiel d'oxydation se situe au-dessus de celui du manganèse VII en manganèse VI, des substances tampons du pH, de préférence des carbonates alcalins primaires et/ou secondaires, tels que le carbonate de sodium et/ou l'hydrogénocarbonate de sodium, ainsi que des polyphosphates résistant à l'oxydation. En outre, l'invention concerne un procédé de nettoyage, de désinfection et de contrôle de la pureté d'installations industrielles ou d'éléments de telles installations, ainsi que l'utilisation d'un agent selon l'invention, en tant que solution d'indicateur, pour la détermination de la pureté d'installations industrielles ou d'éléments de telles installations, par détermination de l'intensité de la lumière émise par la solution dans le domaine violet des longueurs d'ondes.
