Investigation of formation and structural characteristics of the adsorbed layer of organic matter on suspended mineral particles after the examples of gumat Na adsorbtion processes on clay minerals

摘要

Investigation of boundary surfaces in the water ecological systems, processes of formation the adsorbed layers, their sizes and structures is the significant problem of the researches natural water ecosystems. The work is devoted to study of adsorption processes of dissolved organic matter (DOM) on suspended inorganic particles, definition of the approaches to the evaluation of total boundary area of suspended inorganic matter and the volume of influence zone generated by these boundaries, for surface waters as a necessary step for the transfer to the study of chemical and physical processes which are flowing past on these boundaries. Total boundary area of suspended inorganic matter, a thickness and volume of boundary zone, involved surface interactions are estimated. The parameters of organic matter adsorption are investigated, and the character dependencies by the interaction of organic and inorganic matters are defined. The part of adsorbed organic matter (AOM) from a DOM is determinated at a variation of some parameters of a system. Total volume of the adsorbed layer on a surface of the suspended matter is appreciated, the average concentration of AOM in the adsorbed layer is estimated.
