Modeling of binary and ternary batch adsorption systems via multidimensional logistic distribution and statistical physics

In many industrial sites, a series of various organic and inorganic co-contaminant species are simultaneously present in their aqueous discharges. This therefore justifies the recent interest choice binary ternary adsorption three to understand competitive effects. Here we introduced two types theoretical models, recently developed by us: multi-logistic distribution statistical physics. These modeling approaches were applied order cationic dyes (Rhodamine B, RB Malachite Green, MG) one metal cation (Cadmium Cd(II)) on granulated activated carbon (GAC). New experimental batch data obtained with these mono-component, systems. The capacities all pollutants decreased from single Moreover, although Cd(II) did not lead any notable effect, when (binary systems) there was an increase capacity for decrease MG, thus indicating complex removal process due different Both models used calculate affinities, dissociation constants, steric energetic parameters characterize single, binary, tested pollutants. Modeling results indicated that number captured adsorbates per active receptor site GAC systems, signaling effect same site. Based this parameter, orientation described. Interestingly, provided energies which allowed characterization interactions between adsorbent surface. Calculated showed systems associated physisorption.
