Abstract
The proposed model of cation sorption processes with natural organic matter of peat deposits could be applied in a wide pH range. Model testing was produced on the basis of field migration experiment, which was carried out at Lomonosov Diamond Deposit (Arkhangel'sk Region, Russia). It was shown that taking into account the double porosity is necessary for the correct forecast of transport of dissolved compounds in peat.
