Abstract
Results are reported on lab-scale experiments on the removal of Cs-134 and Co-60 from liquid radioactive waste originating from Radioisotope Production Laboratory. Low cost and simple nickel ferro-cyanide preci pitation was applied for the separation of radionuclides from low-leve l radioactive liquid waste. Using the optimal nickel concentration of 0.75M and optimum cyanide concentration of 0.50M about 98% of the Cs-1 34 can be removed at an optimum pH of nearly 10. Furthermore, using th e same method nearly 60% of Co-60 has been removed. The nickel ferrocy anide precipitation method could be used for removal of Cs from low le vel liquid waste.
