Both polar and non-polar substances, such as phenols, aromatic sulfonates, lignin-sulfonic acids, humic and fulvic substances (acids) and mono- and poly-aromatic hydrocarbons, their alkyl-substituted derivatives, respectively, are among the potential aromatic micropollutants. During the last 5 - 10 ...

a7) Wash the non-polar solvent with warm distilled water wash, cool distilled water wash, and a third warm water wash. Continue washing until the washes are clean. After the third wash, monitor the pH and do not allow it to fall below pH 9. If necessary to remove excess sodium ions,...
It is particularly useful for studying a polar environment like water and water-solvated samples. In biological samples, the dielectric relaxation of water is called γ-dispersion, and falls in the microwave range (between 0.5 and 50 GHz)11,12,13 (Fig. 1). Figure 1 Schematic presentation ...
In particular, polar drug molecules prefer to stay in the hydrated environment and avoid hydrophobic double lipid layer environment. In this regard, the transmission systems provide special form mechanism of drug release, which is interesting in terms of application, since they have a large ...
On the contrary, the SSA of low-temperature nanobiochar is relatively low and the polar surface functional groups are relatively more, and the dominant adsorption mechanism is biased towards chemical adsorption (Zhuang et al. 2021). Therefore, to explore the nanobiochar with good removal ability ...
