Study of the sorption activity of sorbents based on alginate and biochar functionalized with metal oxides

Abstract

The largest volume of industrial production of phthalates today falls on two main homologues DBP and DEHP. Due to satisfactory characteristics of phthalates as plasticizers, they have long been involved in the production of polymeric materials for a wide variety of purposes. In the era of active consumption of goods, demand and production of petrochemical products is steadily increasing. And the time interval, in turn, between its production and disposal is decreasing. More and more phthalate-containing materials end up buried in landfills. The rate of their natural degradation in nature through hydrolysis, photochemical processes and the activity of soil consortia of microorganisms is significantly lower than the rate of their production. A negative consequence of the widespread use of phthalates is the widespread pollution of soils, air, surface and groundwater with these substances. Regions of the planet with severely limited water resources are forced to include in their consumption cycles sources whose quality and safety sometimes do not correspond to any sanitary standards. The problem of water conditioning in such cases is of vital importance. Water treatment in such circumstances should be a simple but effective process.
