“…A consequence of the lower SAR and subsequent cation density in the zeolite was the observed affinity and range of heats of adsorption toward water in the Na-SSZ-13 sample studied here. The adsorption isotherm of water at low partial pressures revealed less uptake and affinity compared to other aluminosilicate zeolites. , …”

Adsorption isotherms on Na-SSZ-13, a small-pore zeolite, for pure-component adsorbates CO2, H2O, and C6H14 were measured using a gravimetric adsorption instrument with a temperature range between 30 and 100 °C. These isotherm data were fit to a multisite Langmuir adsorption model. Using the same gravimetric adsorption instrument, binary adsorption isotherms for the adsorbate pairs CO2–H2O and CO2–C6H14 were measured with a temperature range between 30 and 80 °C. These data demonstrated that the increasing loading of either H2O or C6H14 impacted the loading of CO2 on Na-SSZ-13. The binary isotherm data were compared with ideal adsorbed solution theory and showed relatively good agreement between the data and modeling.

“…Its performance is on par with zeolite 13X over all factors considered here. Considering its water co-adsorption and regeneration characteristics are more desirable than zeolite 13X, [67][68][69] it may be a preferred candidate assuming that long-term cyclic stability can be verified. It is possible that the MOFs investigated here display better performance in a TSA process.…”

“…Furthermore, the Langmuir adsorption kinetic model was also used to fit the experimental data from the batch test because, unlike the saturation-growth-rate model, the Langmuir model can cluster different batch assays. The Langmuir model has previously been used to evaluate the adsorption process onto different materials [49][50][51]:…”

This study aims to evaluate the sorption characteristics of NH 4 + -N and PO 4 3 − -P onto the surface of natural zeolites coming from Chile and their potential application in the subsurface-flow treatment wetlands for wastewater treatment in rural areas. For this purpose, adsorption experiments onto the zeolite were developed in batch assays. The effects of the adsorbent quantity (20 g and 50 g) and particle size (0.2–1.0 mm; 1.5–3.0 mm, and 5.0–8.0 mm) were evaluated in terms of adsorption capacity at different NH4+-N and PO4−3-P concentrations. Then, the obtained laboratory results were adjusted to theoretical models: Saturation-growth-rate and Langmuir. The saturation adsorption of NH4+-N on the zeolite increases at the same time that the initial concentration increases for the same zeolite quantity; however, the saturation values were similar between the different zeolite sizes tested. For PO4−3-P, the adsorption did not have a direct relationship with the initial concentration nor zeolite quantity and better results were only achieved for zeolite sizes of 1.5–3.0 mm. Regarding the Langmuir model, sizes of 1.5–3.0 mm had the best adsorption characteristics, with the maximum adsorption capacity of up to 1.58 mg/g for NH4+-N and up to 0.08 mg/g for PO4−3-P. Therefore, a new material—a natural zeolite from the Maule Region of Chile—is described as a potential support medium for treatment wetlands.
