This paper presents the results of a investigations on the possibility of obtaining new sorption materials based on modifying the natural zeolites of the Eastern Transbaikalia deposit, investigation the laws of sorption extraction of heavy metals and oil products from industrial wastewater of railway transport enterprises with a new sorbents. It is shown that chemical modification of natural zeolites allows obtaining sorbents with a more ordered structure compared to natural layered silicates, an increased surface area and a transient nature of porosity, which ensures their high sorption activity and, therefore, the perspectivity of application in the sorption technology of wastewater treatment.
