Zur Charakterisierung von Aktivkohlen durch die Zersetzung von Wasserstoffperoxid

Abstract

Zur Charakterisierung yon Aktivkohlen dureh die Zersetzung von WasserstoffperoxidSunmury: I n search for a suitable and fast analytical method for assessing kinds of activated carbon for water purification t.here were carried out investigations with hydrogen peroxide. According t o their catalytic activity, the various kinds of activated carbon are capable of decomposing hydrogen peroxide t o different degrees and a t different rates. The released oxygen can be determined volumctrically. The results of investigation obtained on always fresh carbon samples with acid a n d bkaic groups were diarussed on the basis of the velocity constants of the oxygen development.An assessment of quality would be possible, in principle, but the surface characterist.ic of the kin& of carbon is considernbly superimposed by influences of morphology, so t h a t applying this method is advised against..
