Nanostructured chitosan/molecular sieve-4A an emergent material for the synergistic adsorption of radioactive major pollutants cesium and strontium

Modeling of aqueous phase adsorption: Is it time to bid adieu to the Harkins–Jura isotherm?

“…One version of the AD isotherm, adapted for aqueous phase adsorption, is written as Eq. (10), where qm and b are the Langmuir constants and kA and nA are fitting parameters. The AD isotherm has recently been shown to fit several aqueous phase adsorption isotherms with high accuracy [30,31].…”

“…A 2004 paper was among the first to apply the HJ isotherm to aqueous phase adsorption data [3]. Since then, many such studies have been published across a broad spectrum of scholarly journals (e.g., Chemical Engineering Journal [4][5][6][7], Journal of Hazardous Materials [8][9][10],…”

Removal of Cd2+ from water containing Ca2+ and Mg2+ using titanate nanotubes modified by carbon

“…Where 𝑘 1 is the rate constant of pseudo-first-order adsorption, 𝑞 𝑒 (mg/g) and 𝑞 𝑡 (mg/g) is the amount of Cd 2+ adsorbed at equilibrium and at time (t) (Goyal et al 2020). The pseudo first order dynamics is as follows…”

Biodegradable chito-beads replacing non-biodegradable microplastics for cosmetics

“…Chitin possesses great mechanical properties (stiffness of > 50 GPa) and solvent resistance including both aqueous and organic solvents, owing to its highly crystalline structure. 36 Furthermore, it is biodegradable as well as biocompatible, and has antibacterial, antifungal, and hemostatic properties. [37][38][39] Therefore, chitin has attracted attention for use as a structural biomaterial for medical and cosmetic applications.…”
