Results and discussion

Preliminary study:
In the incubated samples at pH 4, 7 and 9 no significant reduction of the test item concentration was observed. After the incubation time of 6 days the test item concentration were determined to be higher than 90% of the initial concentrations.
Test performance:
As a consequence of the results of the pre-tests, no further testing was necessary at any pH values.
