Fig. 4. (A) Structural components of SA, (B and C) ionic and covalent crosslinking of SA by divalent/polyvalent ions or appropriate cross-linkers like AAD. SA solution can be converted to a hydrogel by lowering the pH below the pKa value of the guluronic residue or through ionotropic me...
Stage 2: The adsorbate in ionic form (arsenite or arsenate ion) can react with one of the active sites of the adsorbent produced during stage 1. To obtain the best results, the pH of the solution should be basic. Stage 3: The adsorption process occurs during this stage, and the reaction...
We initially focussed on the electrophile 4-toluenesulfonyl chloride (TsCl) considering the strong thermodynamic driver towards S–F bond formation (for example, approximately 380 versus 190 kJ mol−1 for S–X in SO2F2 and SO2Cl2, respectively)27, and their widespread synthetic utility30,31...
As RY84 is a large molecule that contains functional groups that may charge differently in water as a function of pH: they can become positively charged (protonated, methyl, amino) as well as negatively charged (sulphate, chloride) (see Figs. S1 and S2), heaving a zwitterionic character....
Furthermore, one study found that incorporating fillers into a C- S-H gel reduced the amount of proton water in the gel, which, in turn, increased the strength of the chemical bond (ionic bond and covalent binding) between the gel's Ca, O, and Si atom structural groups. However, the...
Accordingly, one may specifically combine a calcium salt such as calcium chloride (CaCl2) with salt of phosphoric acid such as sodium hydrophosphate (Na2HPO4) and form CaHPO4 according to the following general equation: CaCl2.2H2O+Na2HPO4→CaHPO4.2H2O+2NaCl As can also be seen in FIG. 1...
