Nowadays, even more great interest is driven toapplication of natural clay minerals in production of various products, including sorbents for household application. Clays, in form of high dispersed sediment rocks appeared as a result of geological processes, with occurrence of complicated physical and chemical processes. They can be characterized with a great free surface energy which is determined by its sorption properties. Practical application of clays as sorbents is influenced by the size of their specific surface, maximum pore volume, pore distribution by their volumes, adsorption energy and ion exchange capacity. For practical application of clay as a sorbent, it is significant not only to detect its properties, but also possibility to modify them. Only during latest twenty years, an increased attention is driven to clay sorption properties, and their systematic studies are conducted. [1-2]. A special attention is driven to improvement of clay sorption properties which could allow to scientifically develop various sorbents for collection of oil products, like oil spills from the water surface, water procession and cleaning of waste waters from heavy metal ions, organic and non-organic admixtures, etc. In this study, surface properties of Latvian Triassic (Vadakste deposit) and Jurassic (Streli deposit) period smectite-containing clay samples, in order to develop cheap sorbents of high quality, based on these clays, were studied. Using sedimentation method, granulometric composition of natural clay samples was determined. Mineralogical composition of the clay samples was studied, using X-Ray diffraction method. Specific surface sizes were measured using BET method. Surface morphology of the obtained samples was studied, using a scanning electronic microscopy method. Sorption properties of natural Vadakste and Streli deposit clay samples were amended by thermal treatment, as well as by adding a natural modifier based on hemicelluloses and lignin (HLS). Optimal thermal treatment conditions and HLS modification conditions were determined for the natural clay samples. It was found that, with increasing the thermal treatment temperature boundaries from 300,500 until 8000C, specific surface size of the clay samples decreases, causing reduction of the water sorption, however, in the same time, silicone oil and rapeseed oil sorption increases twice. Adding HLS to clays in boundaries from 0,053% to 0,13%, both water and oils sorption increases twice. Ability of natural and modified clay samples to adsorb copper and zinc ions from their salt solutions was researched. The obtained results show that the developed sorbent granules on the clay basis can be used for waste water treatment from copper and zinc ions, for collection of oil and oil-like materials; they can be used as a cheap, ecologically safe pet litter.
