A laboratory procedure is described for the removal of 99.7% of radiostrontium from milk. The batch method uses 3 treatments of the milk with cation exchange resin. One l of milk is mechanically stirred for 20 min with 50 g of Dowex 50 W-X8 resin in potassium form plus 5 g of the resin in hydrogen form. After stirring, the resin is removed by filtration and the filtered mtlk is treated once more for 20 min with fresh portions of 50 g potassium resin and 5 g hydrogen resin. The milk is filtered and stirred for 20 min with the resin in the calcium form plus 5 g resin in hydrogen form. The used resin is washed in water with detergent, sterilized with hot diluted HNO/sub 3/, and transferred to a column for conversion to the sodium form by passing strong NaCl solution through the column. The sodium resin is transferred to potassium resin, calcium resin, or hydrogen resin in three different columns by passing a KCl, a CaCl/sub 2/, or a HCl solution, respectively, through the sodium resin beads. The taste of the treated milk is good and a taste panel of 20 persons failed to distinguish any significant difference between treated and untreated consumer milk. (C.H.)
