摘要：
The results of laboratory investigations into the aerobic biodegradation of chelating compounds in water medium under static test conditions are presented. It was found that nitrilotriacetic acid (NTA) and glutamic acid diacetic acid (GLDA) are more readily biodegradable than ethylenediaminetetraacetic acid (EDTA) commonly used in the production of liquid fertilizers. Biodegradation was evaluated on the basis of compound decay and changes in COD.
