Assessment of Groundwater Quality in the Talensi District, Northern Ghana by Larry Pax Chegbeleh, Bismark Awinbire Akurugu, Sandow Mark Yidana

“…High nitrate and lead levels observed have been associated with agrochemicals and wastewater from farms and homes. Three main flow regimes have been identified with Q-mode cluster analysis, in which mixed cation water types have been revealed, where areas designated as recharge zones are dominated by Na+ + K+–Mg2+–HCO3− fresh water types characterised by low mineralisation and pH, which evolve into Mg2+– Na+ + K+– HCO3− fresh water type with corresponding increased mineralisation of the groundwater. …”

Modification of Chitosan-Coated Magnetic Material with Glycidyl-trimethylammonium Chloride for Cr(VI) Adsorption by Salwa Kamilia, Feri Mukhayani, Sutarno Sutarno, Nuryono Nuryono

“…The study of kinetics and adsorption isotherm showed that the adsorption of Cr(VI) anion on the adsorbent MM/Chit/GTMAC (with the mass ratio of Chit to GTMAC 1:6) follows the pseudo-second-order kinetic model with the adsorption rate constant of 5.3 × 10−3 g mg−1 min−1 and Langmuir isotherms with the adsorption maximum capacity of 104.17 mg g−1, which has a potential to be applied for removing Cr(VI) from polluted wastewater.…”

Uncertainty impact of isotherm models on liquid-phase adsorption thermodynamics: A bayesian inference perspective by Thiago Reschützegger, Nina Paula Gonçalves Salau

“…Liquid-phase adsorption, a fundamental process where molecules in a liquid medium adhere to a solid surface, plays a crucial role in various chemical engineering applications such as wastewater decontamination and solvent recovery. These phenomena can be described by equilibrium models, which offer insight into adsorption capacity and thermodynamic properties, such as enthalpy and entropy variations, yet parameter uncertainty often undermines their accuracy. …”
