Abstract

Interaction between iron(III)-diphosphate and iron(III)-triphosphate and Ca-form of a clayey meadow soil was followed over a period of three days using radiotracer technique and kinetic evaluation of the results performed.⁵⁹Fe served to determine the quantity of iron,⁴⁵Ca to measure the calcium, and phosphorus was measured spectrophotometrically. Approximately 80% of both iron chelates disappeared from the solution during the time of the experiment as a result of two well distinguishable reactions. One of them is a rapid interfacial process of about 10 minutes and the other is a slow reaction leading to the decomposition of iron(III)-polyphosphate chelates. The two processes could be separated using the Christiansen equation.
