XPS and NMR studies of phosphoric acid activated carbons ...
2008-12-1 Chemical structure of phosphorus species in two series of polymer-based and fruit-stone-based carbons obtained by phosphoric acid activation at 400–1000 °C were investigated by XPS and solid state 31 P-NMR and 13 C-NMR. It has been shown that the most abundant and thus thermally stable phosphorus species in all investigated carbons is phosphate-like structure bound to carbon

What happens when acid reacts with limestone? Questions ...
2008-6-15 Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

CITRATE TO PREVENT CALCIUM AND URIC ACID STONES
Up to this point we have considered only increase of urine volume as a means of stone prevention. The effect of increased urine volume is to reduce urine supersaturation with respect to stone forming salts and therefore reduce the risk of crystal formation which is the basis for kidney stones. WHY CITRATE Mechanisms. Supersaturation with respect to the calcium stones depends upon urine ...

Porous Structure of Activated Carbon Prepared from Cherry ...
2007-7-11 Cherry stones (CS), a lignocellulosic material abundantly generated by the agrarian industry in the Valle del Jerte (Cáceres province, Spain), were used as a precursor in the preparation of granular activated carbon by chemical activation with H3PO4. After previous contact with a dilute H2SO4 solution, CS were first soaked in a H3PO4 solution (i.e., at H3PO4-to-CS ratios ranging between 0.64 ...
