Adsorption of sodium lauryl sulfate onto arsenic-bearing ferrihydrite

Applicability of the various adsorption models of three dyes adsorption onto activated carbon prepared waste apricot

“…Frumkin isotherm constants are summarized in Table 2. The positive a values indicate that there is attractive interaction between the adsorbed species [26]. The different a values are attributed to differences in the orientation of the dye molecules.…”

Sorption equilibrium of mercury onto ground-up tree fern

“…Several sorption isotherms have recently been studied for metal removal such as Langmuir [31], Freundlich [32], Dubinin-Radushkevich [5], Frumkin [33], van Bemmelen-Freundlich [34], Sips [35], Ideal Adsorption Solution Theory [36], BET [37], Redlich-Peterson [29], Henry [38], and Tóth [39]. The goal of the present work was to study the possibility of utilizing ground-up tree fern for the sorption of mercury ions from aqueous solutions and the effect of temperature on its sorption of mercury.…”

Adsorption Isotherm Models for Dye Removal by Paliurus spinachristi Mill. Frutis and Seeds in a Single Component System

“…The linear form of this equation can be given as follows: Table 1 Adsorption isotherm constants of two-parameter models for MB adsorption onto PSCFS Frumkin isotherms graphs are given in figure 10 and isotherm constants and isotherm constans with regression coefficient are shown in table 2. The positive a parameter values indicate that there is attractive interaction between the adsorbed species [37]. The different a parameter values are attributed to differences in the orientation of the molecules.…”
