Chemical transformations of Fe(III), Al(III), and Co(II) ions under cohydrolysis in coolants of nuclear power installations

The effect of dosing with aluminum salts of the water coolants of primary circuits at nuclear power installations on the radiation situation at their maintenance area via decreasing the 60Co content in the deposited activated corrosion products was examined. Potentiometric titration, gel chromatographic, and atomic absorption spectrometric techniques were employed for identifying the elemental composition and molecular-weight distribution of the hydrolytic polycondensation products yielded by cohydrolysis of the components of binary, Fe(III) + Co(II) and Fe(III) + Al(III), and ternary, Fe(III) + Al(III) + Co(II), mixed solutions (systems).
