Ozone Solubility in Aqueous Solutions of NaCl, Na₂SO₄, and K₂SO₄: Application of the Weisenberger-Schumpe Model for Description of Regularities and Calculation of the Ozone Molar Absorption Coefficient

Development and Validation of the Successor to the Weisenberger–Schumpe Solubility Model of Gas in Aqueous Electrolytes: Solubilities of Ar, He, Xe, and O3 in Electrolyte Solutions at 25 °C

“…Under these conditions, the ratio of the change in K S to Δ K Y–X,1‑1 should vary from 1 for Δ K Y–X,2‑2 /Δ K Y–X,1‑1 to 2.5 for Δ K Y–X,3‑3‑2‑2‑2 /Δ K Y–X,1‑1 . To calculate these ratios, we used the results reported in the present and previous studies. − …”

“…Xe (99.9999%) was supplied by a medical Xe manufacturer (LLC Akela-N, Moscow, Russia). Some of the employed solutions had been used in previous works, 12,13 while others were prepared using fresh triple distilled water with a resistance of ≥18. •xH 2 O did not exhibit a significant weight loss, whereas a marked weight loss was observed at 200 °C (in which case, the weight stabilized within 38 h).…”

“…The experimental setup and the procedure used to determine ozone solubility have been described elsewhere. , A modified setup was used for the preparation of oxygen and the purification of ozone–oxygen mixtures. Prior to being fed into an UOTA-60-1 ozone generator (LLC firm “Medozon”, Moscow, Russia), oxygen was passed through VentiSorb soda lime [Flexicare (Group) Limited, UK] to remove CO 2 traces.…”

“…Xe (99.9999%) was supplied by a medical Xe manufacturer (LLC Akela-N, Moscow, Russia). Some of the employed solutions had been used in previous works, , while others were prepared using fresh triple distilled water with a resistance of ≥18.2 MΩ. Reagents grade (purity: >98%) Al 2 (SO 4 ) 3 · x H 2 O and K 2 HPO 4 were obtained from Sigma-Aldrich.…”

“…The parameters h i and h G,Y were determined using the most reliable set of 43 experimental K S values obtained for electrolytes of 1-1 to 3-3-2-2-2 valence types. Out of these, 38 constants were taken from the present study and our previous works, 12,13 while the other five constants were taken from the works of other authors: K S,Ar = 0.1067 L mol −1 in LiCl, 18 K S,Ar = 0.1437 L mol −1 in NaCl, 18 K S,Ar = 0.0957 L mol −1 in LiCl, 19 K S,Ar = 0.1415 L mol −1 in NaCl, 19 and K S,Ar = 0.1298 L mol −1 in KCl. 19 It should be noted that the K S for ozone in HClO 4 solutions was estimated to be −0.0172 L mol −1 when the initial concentration was in the range 0−1 mol L −1 .…”
