SLP,MexicoIn this work, we use the self-consistent generalized Langevin equation theory of dynamic arrestfor colloidal mixtures (SCGLE)[1], we study the diagram of dynamic arrested states and dynamicproperties of colloidal systems immerse in a porous media. We report the diagram of dynamicarrested states for a fluid with atractive interactions of the Yukawa type immerse in a porous mediaof hard spheres. We use the mean spherical approximation (MSA), for the calculation of structurefactors S(k), which are the only external input necessary to solve SCGLE. We considerer a systemof two species of particles of hard-core diameters. One is considered fluid and the other is theporous media and this system is determined by temperature T , the fluid volume fraction φf, theporous media volume fraction φm, and the potential range z. We obtain that when we increaseφm the dynamic arrest curve appears at lower fluid volume fractions. This fact favors the dynamicarrest. Also when have φm = 0.21, we get islands of liquid states when the temperature decreases.[1] R. Juárez-Maldonado and M. Medina Noyola, Phys. Rev. E 77, 051503 (2008)93
