- W2378645303 abstract "90Y,which decays by 90Sr,is one of the most feasible radionuclides for cancer treatment.In recent years,studies of the utilization of 90Y separated periodically from the 90Sr-90Y isotope addition method cow for treating diseases of the bone cancer,cancer of the liver,breast cancer and ovarian cancer had become the research focus in the world.In this paper,researches on separation of strontium-yttrium solution by self-made polyantimonic acid inorganic ion-exchangers were carried through,and initial researches on real 90Sr-90Y generator were attempted.The experimental results showed that the obtained ion-exchange material has better adsorbability for strontium.The exchange and adsorption capacity for strontium is about 0.79 mmol·g-1 in Sr2+-Y3+ solution under 0.01 mol·L-1 nitric acid solution conditions,and for yttrium only 0.01 mmol·g-1.And adsorption of polyantimonic acid for strontium is a coexisted course for both chemical exchange and physical adsorption.The adsorption reaction order of polyantimonic acid for strontium under 293 K is 1.28 while it is 2.46 under 313 K.In addition,the maximum distribution coefficients of polyantimonic acid for stable Sr2+-Y3+ in fixed bed reaction can reach 1.3×107." @default.
