“…Because of decrease in adsorbate concentration during adsorption process a i values are negative. As reported [1][2][3], at each constant temperature, ʋ 0i and i a values decrease from the first to the second region and in each region their values increase with increase in shaking velocity. Also, in each region, ʋ 0i and i a values increase with increase in temperature [1,2].…”

At first, the KASRA model and KASRA equation are discussed [1][2][3]. KASRA is an abbreviation for "Kinetics of Adsorption Study in the Regions with Constant Adsorption Acceleration". The KASRA model was presented by Samiey [1] in 2013 and is based on the following assumptions: (1) each time range with constant adsorption acceleration, is named a "region", (2) there are two regions before attaining plateau region, (3) the boundaries between the first and second regions and the second and third (plateau) regions are named "starting second region" (abbreviated as ssr) and "kinetics of adsorption termination" (abbreviated as kat) points, respectively and are determined by the KASRA equation, (Figures 1-4). Due to different features of the first and second regions, parameters obtained from a kinetic equation (such as the pore-diffusion, Avrami and Elovich equations, etc.) for these two regions are different from each other and the related equations for these regions come different pathways to the point q t =0 at t=0 (or q 01 according to the KASRA model). It is good to say that KASRA is a Persian word meaning king. AbstractIn different concentration ranges of adsorbed species, various interactions occur between them and surface adsorption sites and there are different regions in an adsorption isotherm. In the common method for study of adsorption process, all of these regions are considered as one region and thus there are concerns regarding using adsorption equations. In this work, based on the KASRA and ARIAN regional models, a new method is presented for analysis of adsorption kinetic and thermodynamic data, respectively. The KASRA and ARIAN models are three-and four-region models, respectively and adsorption equations are used on the basis assumptions used in these models. According to the ARIAN model, adsorption binding constant of each region of an adsorption isotherm is different from the other regions. On the other hand, based on the kinetic KASRA model and ideal-second-order (ISO) equation, during the adsorption in each initial adsorbate concentration, different interactions occur between adsorbate species and adsorbent surface sites and thus the observed adsorption binding constant is an average value of these binding constants.

“…In addition, Freundlich and Langmuir isotherm are also employed to describe the reaction of methyl orange onto PMMA/zeolite nanofibrous membrane and to determine the maximum adsorption capacity of the PMMA/zeolite nanofibrous membrane. The linear form of Freundlich isotherm is as follows:

\ln q_{e} = \ln K_{F} + \frac{1}{n} \ln C_{e}

where, q e is the amount of methyl orange adsorbed per unit of adsorbent at equilibrium (mg g −1 ), K F and n are Freundlich constant indicating the capacity of the adsorbent (mg g −1 ) and the intensity of the adsorption process. K F and n values were calculated from the intercept and slope of the linear plot of ln q e versus ln C e .…”

The present work investigates the effect of various solution parameters and electrospinning parameters on the characteristics of electrospun nanofibrous membranes. Scanning electron microscopy was used to analyze the surface morphology of the nanofibrous membrane. Adsorption test on methyl orange was also carried out and analyzed using the UV–vis. Results showed that increasing voltage decreased mean nanofiber diameter. Meanwhile, increasing PMMA concentration, feed rate, distance between collector‐and‐needle tip increased mean nanofiber diameter. Zeolite concentration and needle size did not affect the surface morphology significantly. The UV–vis spectra of the adsorption test showed that ∼93%, 85.5%, and 78% of methyl orange were adsorbed for 30, 50, and 100 mg L−1 initial dye concentration, respectively, within 11 min. The maximum adsorption capacity was found to be 95.33 mg g−1. Therefore, PMMA/zeolite nanofibrous membranes possess the adsorption capability toward effective dye removal. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44450.

Experiments were performed to characterize the adsorption of the cationic surfactant benzalkonium chloride (BZK) on polyester as well as measure the effect of the cationic surfactant on polyester surface charge. Additional studies were performed to examine the effect of adding nonionic surfactants on surface charge. In studies of adsorption of BZK on polyester, different behaviors were observed at pH values 6 and 10, with adsorption reaching a maximum at pH 10 but not at pH 6. In probing the zeta potential and isoelectric point (IEP) of polyester exposed to solutions composed of BZK (cationic surfactant) and an ethoxylated alcohol (nonionic surfactant), it was seen that the IEP could be shifted to higher pH levels by increasing the mole fraction of nonionic surfactant in a cationic/nonionic surfactant solution. A maximum in the IEP was obtained at a certain mole fraction for most cases. The shift in the IEP was hypothesized to be driven by increased deposition of the cationic, since the nonionic itself did not significantly change the IEP. The cooperative interactions between cationic and nonionic species were theorized to be driven not so much by attractive interactions, but other interactions, such as minimization of cationic charge repulsion.
