Description of key information
Adsorption/desorption:
Adsorption studies were conducted using initial concentration 0.00001 mol/L of test chemical at 25°C. Adsorption, in terms of sorption on granular goethite (30-50 mesh) was investigated with goethite at concentration 0.003 g/L. Both goethite and test susbtance were suspended in water. Samples were filtered and analysed by HPLC, UV-VIS. The fractional sorption of test chemical was calculated as 4 %. This value indicates the low adsorption potential of the chemical.
Additional information
Adsorption/desorption:
Experimental studies for test chemical have been reviewed for adsorption endpoint and their results are summarized below.
The first experimental study was reviewed from journal Water Research (2002) in this study the adsorption in soil was determined using initial concentration 0.00001 mol/L of test chemical at 25°C. Adsorption, in terms of sorption on granular goethite (30-50 mesh) was investigated with goethite at concentration 0.003 g/L. Both goethite and test substance were suspended in water. Samples were filtered and analysed by HPLC, UV-VIS. The fractional sorption of test chemical was calculated as 4 %. This value indicates the low adsorption potential of the test chemical.
Next both the studies were reviewed from authoritative database (HSDB, 2018) in first study the Koc value for test chemical was estimated by using a structure estimation method based on molecular connectivity indices. The estimated Koc value was 90 dimensionless and log Koc is 1.9542 this log Koc value suggests that test chemical is expected to have low sorption to soil and sediment and therefore have moderate migration potential to ground water.
In another study the percent adsorption of test chemical on organoclay is 12% at pH 7.7. On the basis of percent adsorbed of test chemical it can be concluded that test chemical has low sorption to organoclay and moderate migration potential to ground water.
By considering results of all the studies mentioned above it can be concluded that test chemical has low sorption to soil and sediments and therefore has moderate migration potential to ground water.
