Adsorption / desorption

The adsorption coefficient of zinc, 5,5'-azobis-2,4,6(1H,3H,5H)-pyrimidinetrione complexes and melamine was determined by HPLC according to OECD Guideline 121. The determined log Koc was 0.821 measured at 30 °C. Zinc, 5,5'-azobis-2,4,6(1H,3H,5H)-pyrimidinetrione complexes and melamine has a negligible sorption potential to soil and sediment.
