The Halsey isotherm for water contaminant adsorption is fake

We present a critique of the Halsey isotherm model (also known as Frenkel–Halsey–Hill), which is used by many researchers to interpret water contaminant adsorption data. first convert original for gas-phase form appropriate liquid-phase adsorption. call this version “genuine isotherm.” then show that currently in research bears only partial resemblance genuine isotherm. As such, we label former “fake go on prove fake mathematically equivalent Freundlich Consequently, modeling results obtained reported numerous previously published studies have been mostly misleading. Many such reports can be found across broad spectrum major journals. Finally, highlight data-fitting attributes It shown capable describing isotherms having types I, II, and III curve shapes.
