“…Redlich-Peterson isotherm [45] is a hybrid featuring both Langmuir and Freundlich isotherms, which incorporates three parameters into an empirical equation [46]. The model has a linear relationship with concentration in the numerator and an exponential function in the denominator [47] To represent adsorption equilibrium over a wide concentration range, such a model can be applied either in homogeneous or heterogeneous systems due to its versatility [48].…”

In this study, an intelligent architecture-based neuro-fuzzy technique is used for the prediction of removal capacity of Cu(II) and Cr(VI) from aqueous solution using wheat straw as a biosorbent. The effect of operating parameters such as initial pH, temperature, contact time, straw particle size, and biosorbent's chemical treatment are studied to optimize the conditions for maximum removal capacity. A large database is collected from the different carried out experiments to allow the modelization of the adsorption process. This process could be described using classical mathematical models such as Langmuir, Freundlich, or a hybrid model. However, the learnt neuro-fuzzy architecture with the obtained experimental data presents good correlation (R 2 ¼ 0:9999) and shows that the intelligent model is able to predict accurately the removal amount of Cu(II) and Cr(VI) from wheat straw under different conditions.

“…The Redlich-Peterson isotherm model (R-P) (Prasad and Srivastava 2009) is a hybrid isotherm that approaches the Freundlich model at high concentrations(g tends to zero) and the Langmuir model at low concentrations (g tends to one); this isotherm is therefore often used as a compromise between the Freundlich the and Langmuir models. The R-P isotherm equation is expressed by the following equation:…”

The retention of a pharmaceutical compound, Tiemoniummethylsulfate (TIM), from aqueous solutions by adsorption onto activated carbon prepared from date stones (AC-DS) was investigated. Physical and chemical characteristics of this material were also determined. Results showed that pH 8 was optimal for TIM adsorption. Among the kinetic models considered, the pseudo-second order model was the most appropriate to describe experimental data. Regarding adsorption isotherms, it was shown that the Sips model accurately describe the sorption of TIM onto AC-DS with a correlation factor R 2 > 0.98. The adsorption capacity of (AC-DS) was found to be 42.2mg g 1 at 10°C and 60.5mg g 1 at 25°C, confirming its efficiency for the removal of this compound from aqueous solutions. The values of ΔG 0 and ΔH 0 confirmed that the adsorption of TIM onto AC-DS was spontaneous and endothermic in nature, and hence more effective at high temperatures. An irregular increase in the randomness was suggested at the AC-DS-solution interface during the adsorption process for positive values of ΔS 0 .

“…Fly ash is a major coal-combustion by-product generated in thermal power plants in huge quantities. The global annual fly ash production is about 700 million tons (Krishna Prasad and Srivastava 2009a). Although a significant amount of this portion is being valorized in different applications, such as a substitute for cement in concrete, still, huge quantities are not being utilized and require more proper disposal actions.…”
