Isotherms for adsorption of boron onto new fibrous adsorbent containing glycidol ligands: Linear and nonlinear regression methods

The most appropriate way to design and evaluate an adsorption system performance is by having an idea of the equilibrium relationship, which is also known as adsorption isotherms. The adsorption isotherms provide information on how pollutants such as boron are interacting with adsorbent materials. A...
