Détermination des solubilités de l'ozone dans l'eau et dans une solution aqueuse de chlorure de sodium; calcul des solubilités de l'ozone atmosphérique dans les eaux
Abstract:50. Determination des solubilites de l'ozone dans l'eau et dans une solution aqueuse de ehlorure de sodium; ealeul des solubilites de l'ozone atmospherique dans les eaux par E. Briner et E. Perrottet. (13. 11. 39.) Sur la solubilitk de l'ozone dans l'eau on ne trouve, dans les mkmoires et dans les tables, que des valeurs peu noinbreuses et assez discordantes j certaines de ces donnBes se rapportent d'ailleurs B des mesures dkjQ anciennes.

“…Intact chloroplasts were used as described in "Materials and Methods' with approximately 85%c intact, as judged by microscopic examination. 2 Ferricyanide reduction was assayed as described in Figure 1. The rate of ferricyanide reduction without gassing and without rupturing was 212 ± 12 lAeq /mg Chl-' -hr'1.…”

“…We believe that this dose is, in fact, physiological for aqueous solutions since most of the ozone (90%) passes through the solution unchanged. Indeed, the actual ozone concentration within the solution is governed by the partial pressure of the ozone above it (2). From the Bensen coefficient of ozone at 0 C (2) and the partial pressure of ozone above the aqueous solution, the ozone concentration within the solution can be calculated to be about 10 fIM.…”

“…7 Aldaz and other authors in their study assume that ozone is destroyed at the time of collision at the surface, and didn't consider any diffusion of ozone into the water or decomposition in water. Ozone has a Henry••s •Law coefficient in distilled water of 3.3 at 2s 0 c (19,20).…”

“…The value for the liquid phase exchange constant appropriate to sea surface is .0056 cm/sec (18). Aithough Liss did not consider the case for ozone, the situation should be almost the same because of low solubility (19,20) and reactivity.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
