Soil Adsorption / Mobility

Using a structure estimation method based on molecular connectivity indices(1), the Koc of d-methamphetamine can be estimated to be 900(SRC). According to a classification scheme(2), this estimated Koc value suggests that d-methamphetamine is expected to have low mobility in soil. The pKa of d-methamphetamine is 9.87(3), indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).
