“…In explaining the dependence of the PBMA adsorption on the adsorbent/solution ratio [22], in addition to polarity, which governs the polymer affinity to the adsorbent surface, one should take into consideration the percentage of the low-molecular-mass and high-molecular-mass fractions in the initial polymer. MMD curve of the initial PBMA has a bimodal distribution (Fig.…”

“…Therefore, under the PBMA adsorption, a great number of irreversible adsorbed low-molecular-mass fractions and active mediummolecular-mass fractions pass onto the adsorbent surface at all the investigated adsorbent/solution ratios. Calculation of the adsorption value per unit of the surface gives the following adsorption results: minimum value of adsorption is observed at the maximum quantity of adsorbent [22].…”

Modeling of adsorption isotherm of a binary mixture with real adsorbed solution theory and nonrandom two‐liquid model

in Wiley Online Library (wileyonlinelibrary.com).Gas-phase adsorption equilibria of diluted mixtures of methyl-ethyl-ketone and isopropylanol on activated carbon were investigated. Experimental isotherms were determined by a constant volume method. Single-component adsorption isotherms were fitted by the frequently used Toth model with good accuracy. Then adsorption isotherms were determined for different binary mixtures (with different initial ratio of the two components). Binary mixtures adsorption isotherms were calculated using the adsorbed solution theory. Ideal adsorbed solution theory (IAST) could not represent experimental data, but it was observed that increasing amount of MEK led to higher nonideality of the mixture. Then UNIversal QUAsi Chemical (UNIQUAC) and nonrandom twoliquids (NRTL) models were considered to describe activity coefficients of the adsorbed phase. The fitted parameters of UNIQUAC model depend on the ratio of the two components, whereas the NRTL model is able to fit all experiments with the same parameters, whatever the initial ratio may be.
