Abstract
A process for removing dissolved radioactive materials from aqueous solution by incorporating lime in a sufficient dosage to adjust the pH of the water to greater than 11.0 while simultaneously adding a material from the group consisting of hydrogen peroxide, oxygen, ferrous sulfate, ferric chloride and potassium permanganate.
Claims6
A process for decontaminating a water solution having contained therein naturally occurring radioactive materials having both alpha and beta activity, said solution having a pH of less than 11.0, comprising the following steps:
- adjusting the pH of the solution to at least 8.0;
- incorporating lime into the solution to obtain a pH of greater than 11.0, the dosage of lime being on the order of 110 mg/l;
- simultaneously incorporating with the lime approximately 6.0 mg/l of hydrogen peroxide and rapidly mixing said solution;
- slowly mixing said solution for a period of about twenty minutes to thereby form colloidal particles in said solution;
- and separating the colloidal particles from the solution.
A process for decontaminating a water solution having contained therein naturally occurring radioactive materials having both alpha and beta activity, said solution having a pH of greater than 11.0, comprising the following steps:
- incorporating lime and a 6.0 mg/l dosage of hydrogen peroxide into the solution until a precipitate is observed;
- and separating the precipitate from the solution.
