Adsorption/Desorption:

The soil adsorption coefficient of benzenesulfonic acid, di-C10-14-alkyl derivs., sodium salts was determined by the computer program KOCWIN v2.00 (EPIWIN software v4.11) by US-EPA (ATL, 2017).The EPIWIN estimates the organic carbon-normalized adsorption coefficient for soil (and for sediment), which is designated as Koc. Two different models are used for this estimation: the Sabljic molecular connectivity (MCI) method as well as with the traditional method which is based on logPow. The traditional method gives a logKoc of 5.793 and the MCI method reveals a comparable value of 7.101 as result. The MCI method is taken more seriously into account due to the fact, that it includes improved correction factors.
