Hydroxyl (O-H) confiança 1,0
“from 20 minutes' contact time to 120 minutes for both 4 3615cm-1 The band at was due to O-H stretching, and a granules is due to the fact that initially all adsorbent sites”

Hydroxyl (O-H) confiança 1,0
“Apparently, the new groups are formed as a result of at 3615 cm-1 of the sample in a vacuum led to a diminishing of the OH band intensity, while no other the decomposition of ammonium ions with the liberation of ammonia.”

Hydroxyl (O-H) confiança 1,0
“For all spectra, there were large and broad bands found near 3615 cm-1 and cm-1, and 3419 which was ascribed to the stretching vibration of hydroxyl (O-H).”
