Summary: This study explored the use of Agave americana fibers for the preparation of activated carbon via chemical activation with phosphoric acid, and investigated the effects of preparation conditions on the adsorption capacity towards Alpacide Yellow. The optimal conditions for enhanced properties were found to be an impregnation ratio of 40 g/1 g, impregnation time of 6 h, and carbonization temperature of 400 degrees C. Despite its lower specific surface area compared to commercial activated carbon, the prepared activated carbon exhibited higher adsorption capacity due to the presence of pores and functional groups on its surface. The adsorption process followed a fractal kinetic model, while the adsorption isotherm model was stochastic.

Summary: The removal of Congo red dye from aqueous solutions using different adsorbents was investigated in this study. The results showed that the type of adsorbent influenced the optimum pH and time required for adsorption. The adsorption properties of the dye were best described by the Langmuir isotherm, and the pseudo-second-order kinetic model provided a good fit for the adsorption process. The presence of functional groups and active sites on the adsorbent contributed to its high affinity for the dye. The study suggests that the prepared adsorbents can be cost-effective and efficient for dye removal.

Summary: This study focuses on the removal of crystal violet (CV) dye from water using prepared nickel ferrite nanoparticles (NiF-NPs) with an average size of 28 nm. The CV dye is toxic, carcinogenic, and mutagenic, and its persistence in the environment without degradation can greatly impact living organisms. The experimental data fits well with the Freundlich isotherm model, indicating multilayer coverage of NiF nanoparticles. The adsorption of CV dye is found to occur through physical-sorption process based on the Dubinin-Radushkevich isotherm model.

Summary: This study quantifies the contributions of adsorption, bioreduction, and desorption in EPS-mediated U(VI) immobilization. Experimental results show that U(VI) immobilization is faster when exposed to H-2 compared to O-2. The kinetic model reveals that adsorption is dominant in the first minute, bioreduction is dominant from the second minute to the 50th minute, and after 50 minutes, bioreduction is balanced by desorption. This study also provides the first set of equilibrium data for U(VI) adsorption by EPS alone and shows that U(VI) adsorption onto EPS is endothermic, spontaneous, and favorable at higher temperatures.
