Abstract

In the presence of a stabilising colloid Malachite Green and phosphododekamolybdate acid form a dyestuff salt. When the excess of the Malachite Green has reacted in acid solution to colourless products, the remaining colour is a measure for the phosphate quantity. The method permits the determination of 10–1200 μg of phosphate/l.

Zusammenfassung

Aus Malachitgrün und Dodekamolybdatophosphorsäure wird in Gegenwart eines Schutzkolloids ein stabiles Farbstoffsalz gebildet. Nach dem der Malachitgrünüberschuß im sauren Milieu zu farblosen Produkten abreagiert hat, ist die verbleibende Färbung ein Maß für die PO4 3−-Menge. Photometrisch lassen sich danach 10–1200 μg PO4 3−/l bestimmen.
