摘要
The study of 106Ru behavior in 5, 10 and 16 g dm−3 boric acid solutions in a wide pH range carried out by three different methods revealed the regions of the radionuclide ionic and non-ionic species formation. The strong concentration-dependent boric acid effect on the physicochemical state of 106Ru leads to the destruction of larger ruthenium pseudo-colloid species and formation of smaller ones with neutral or negative charge in pH range 7.0–10.5. The formation of 106Ru complex compounds with ionic forms of boric acid–borate (polyborate) is discussed.
