Verfahrens-Dokument
Soil extracts are injected into a 1M Ammonium acetate carrier and mixed with an acidic solution of o-cresolphthalein complexone and 8-hydroxyquinoline. Calcium is complexed by the ocresolphthalein and magnesium interference is eliminated by adding 8-hydroxyquinoline as a magnesium chelating agent. The pH is then raised to about 10 and the purple colored complex produced is proportional to the calcium concentration.
