Description of key information

Adsorption / desorption

The adsorption coefficient Koc in soil and in sewage sludge of test chemical was determined by the Reverse Phase High Performance Liquid Chromatographic method according to OECD Guideline No. 121 for testing of Chemicals (Experimental study report, 2017). A test item solution was prepared by accurately weighing 5 mg of test item and diluted with ACN up to 10 ml. Thus, the test solution concentration was 500 mg/l. The pH of test substance was 4.93. The reference substances were chosen according to Functional similarity with the test substance and calibration graph prepared. The reference substances were 4-methylaniline(p-Tolouidine), Aniline, Xylene, Ethylbenzene, Toluene, Naphthalene having Koc value ranging from 1.9 to 2.75. The Log Koc value of test chemical was determined to be 2.0625 ± 0.000at 25°C.This logKoc value indicates that the test chemical has a low sorption to soil and sediment and therefore have moderate migration potential to ground water.
