Nanoparticles (NPs) represent emerging pollutants that still pose analytical challenges for their detection in environmentally relevant samples due to extremely low concentrations, high colloidal background, and the need perform speciation analysis. They are also one of interfering matrices during analysis metal ions contaminants water samples. Currently, conventional techniques such as Transmi...
Abstract The paper investigates applicability of two mathematical models developed by the authors for calculating process long-term impregnation coal samples. A distinctive feature studied samples is low porosity. Considered are based on single- and three-channel representation internal structure a porous medium. These were previously used to study highly materials. At same time, model in most ...
