“…Moreover, in the case of pseudo first order kinetics, the calculated Q e differs too much from the experimental values. 55 Hence, it can be asserted that the adsorption process follows pseudo second order kinetics, which indicates that the rate limiting step is achieved by chemisorption affecting the valence change through sharing or electron exchange between the adsorbent and fluoride.…”

“…The Thomas model describes the adsorption capacity of the flowing liquid adsorbate onto the adsorbent in the fixed-bed column. The curve-fitting equation is given below where C is the effluent concentration at time t , C 0 is the feed concentration in ppm, k Th is the Thomas rate coefficient, q e is the amount of As adsorbed onto the adsorbent in mg g –1 , x is the adsorbent mass, and Q is the volumetric flow rate.…”

“…The Adams–Bohart model provides a dynamic relationship for the concentration of the flowing adsorbate in the fixed-bed column. The curve-fitting equation is given below where k AB is the Adams–Bohart rate coefficient, N 0 is the As saturation concentration adsorbed onto the packed bed in mg L –1 , z is the packed bed length, and F is the linear velocity.…”

“…Bohart and Adams first introduced this model in 1920, while studying the adsorption of chlorine on charcoal, based on maximum adsorption capacity (N 0 ) and kinetic constants (k AB ). This model explains the overall isotherm and the relationship between the effluent concentrations over the time and the initial concentration [33]. The linearized structure of the Bohart-Adams model is explained by Equation ( 2).…”
