摘要：

An improved W-188-Re-188 gel generator based on Zr tungstate is described. The influence of synthesis parameters and pre-treatment conditions on Re-188 elution yields and the W-188 breakthrough was studied with 0.15M aqueous solution of NaCl at pH 5.3 to 7.3 as well as with some organic solvents. An elution efficiency of 80% was achieved during 3 month of explotation with 0.15M NaCl at pH = 6.3. The W-188 breakthrough was 10(-4) to 10(-3)%. The W-188 breakthrough may be decreased to 10(-6)% when converted into tandem generator with an alumina column. However, Re-188 yields are reduced by 8-12% with a tandem generator.
