with tea connoisseurs and health enthusiasts reciating its unique qualities. It is often enjoyed in its loose leaf form or brewed using a Yixing clay teapot. Some aficionados even collect aged Pu'er tea, considering it an investment, as the value of certn aged teas can reciate significantly ...
It was reported that Ca2+ was able to flocculate the natural organic matter (NOM) present in the water by cross-linking carboxylic and other functional groups within the organic matter and then with clay particles in the sediment. Using the same theory, the authors explained their observation ...

Potassium ion is fixed by clay minerals and participates in the formation of secondary minerals, and this could explain the low K+ levels (Scheytt 1997). The seasonal variation showed that Na+ concentrations in all the sampled locations were significantly higher (p < 0.05) in rainy ...

(376 rows and 487 columns) with a discretization of 100 × 100 m. The first, third and fifth layers are dominated by sand with relatively large hydraulic conductivities, while the second and fourth layers are dominated by clay with lower hydraulic conductivities (Fig.3). The uppermost ...
. The first weight loss of 14.6% observed below 170 °C, associated with a first endothermic peak at 130 °C in the DTA curve, is ascribed to the evaporation of physically adsorbed water; gelling boehmite or pseudo-boehmite showed an excess water weight loss of 15% [...
This color change is characteristic, due to the presence of clay minerals that are transformed into ceramic minerals with temperature increase [53]. The percentage of mass lost is low due to thermal activation (17.68%), if compared to what is reported in the literature [30,42,54]. This ...
Water may be thickened by adding a suitable amount of bentonite, clay or drilling polymers. This presents the additional advantage of sealing the walls, thus limiting water and pressure losses. Water coming out flows into a mud pit, where the drilling cuts are allowed to decant before the ...
