Modeling Urotropine adsorption thermodynamic on kaolinite particles.

ABSTRACT: This research looked at how much Urotropine can be adsorbed by kaolinite particles and the thermodynamics of that process. Since Urotropine is important for gel injections and stabilizing clay, understanding how it adsorbs onto clay can help us accurately model various related processes. Initially, X-ray diffraction (XRD) analysis was conducted on kaolinite samples, verifying their high purity (97%) and correct crystal structure. Subsequent experiments focused on the adsorption of Urotropine from solutions of varying concentrations onto the kaolinite particles. By monitoring Urotropine's concentration in the aqueous solution with a UV device, we observed that kaolinite efficiently adsorbs Urotropine, reaching an adsorption capacity of 112 mg/g. Notably, the Langmuir adsorption isotherm mod
