Description of key information

Additional information

In standard biodegradation screening tests, including several ready biodegradation tests, no detectable biodegradation of DTPA was observed. In several studies, increasing the sludge age or increasing the pH of the test system resulted in some degradation of the DTPA. Pre-treatment of wastewaters containing DTPA using various oxidation processes can result in degradation of the compound.
