A bench-scale system to continuously separate and concentrate SO{sub 2} from flue gas has been developed and tested. The separation is accomplished due to the relative adsorption strengths of SO{sub 2} and water on a synthetic mordenite, a phenomenon

Iron oxyhydroxides, commonly known as ferrihydrites, are unable to remove dissolved heavy metals at acidic pH, especially below 5.0, due to fierce competition from hydrogen ions. A new hybrid iron-rich inorganic sorbent has been identified and extens

The ability to separate and concentrate SO[sub 2] from a gas stream similar to coal-derived flue gas is accomplished due to the relative adsorption strengths of SO[sub 2] and water on a synthetic mordenite, a phenomenon known as rollup. Laboratory ex

A new material, mordenite synthesized from volcanic ash (perlite) in the presence of sodium salts, has been shown to be a weak sorbent for NO and a strong and reversible sorbent for SO 2 . The mordenite's capacity to adsorb SO 2 was found to be relat

Raman spectroscopy has been used to distinguish the individual carbonate minerals belonging to the calcite, dolomite, and aragonite structural groups. With the use of the in situ laser microprobe technique, it is demonstrated that particle-size effec

The compressive strength of water soaked diabase is found to be about 60% of that of diabase dried at temperatures greater than 190°C. Several solvents other than water failed to cause a decrease in the strength of diabase. This suggests that water

Unit cell dimensions of hydroxylapatite synthesized hydrothermally are a 0 = 9.42 6 A and c 0 = 6.88 5 A, whereas carbonate apatite (2.29 CO 2 ) gave a 0 = 9.43 6 A and c 0 = 6.88 5 A. A deficiency of both calcium and phosphorus in the carbonate apat
