This study describe the adsorption of two cationic dyes (Methylene blue and Rhodamine 6G) from aqueous solutions on to Iraqi porcelanite rocks as adsorbent .A series of experiments were undertaken in a batch adsorption technique to access the effect of the process variables i.e contact time,...

The distributions of citations L, two- (IF2) and five-year impact factors (IF5), and citation half-lives λ of journals published in different selected countries are analyzed using Langmuir-type relation: yn=y0 {1−αKn/(1+Kn)}, where yn denotes Ln, IF2n or IF5n of n-ranked journal, y0 is the...

The citation distribution of papers of selected individual authors was analyzed using five mathematical functions: power-law, stretched exponential, logarithmic, binomial and Langmuir-type. The former two functions have previously been proposed in the literature whereas the remaining three are...

In the present work, a generalized lattice-gas model to study multilayer adsorption of interacting polyatomic species on heterogeneous surfaces is introduced. Using an approximation in the spirit of the well-known Brunauer–Emmet–Teller (BET) model, a new theoretical isotherm is obtained in...

Adsorption thermodynamics of interacting particles adsorbed on one-dimensional channels arranged in a triangular cross-sectional structure is studied through Bragg–Williams approximation (BWA), Monte Carlo (MC) simulations and the recently reported Effective Substates approximation (ESA) [J.L....
