New data on the effect of radioactive radiation on solids and external radiation on some heterogeneous chemical processes

Summary

• 1. New data are presented on the effect of the radioactive radiation of S³⁵ on the rate of isotopic exchange of sulfur at high temperature in the systems$K_2 \mathop S\limits^* O_4 - SO_3$ and$Na_2 \mathop S\limits^* O_4 - SO_3$ and of oxygen in the system$Na_2 \mathop S\limits^* O_4 - O_2 ^{18} .$ External irradiation with high-energy electrons only affects the rate of isotopic exchange at higher doses than radioactive radiation.

• 2. Irradiation of barium sulfate with high-energy electrons and protons leads to a fall in its sorption powers with respect to organic dyes. The prolonged β-decay of S³⁵ forming part of the sorbent has an analogous effect.

• 3. Potassium sulfate containing S³⁵ has a higher sorption power for methanol vapor than inactive K₂SO₄.

• 4. New data are presented on the effect of added radioactive isotopes on the catalytic activity of catalysts.

• 5. Radioactive radiation affects the solution and solubility of sparingly soluble substances.
