Study On The Adsorption Of Nanometer Active Carbon To Radionuclide P³² And I¹³¹

Objective: To study about the adsorption of nanometer active carbon (CarbonNanoparticles Suspension Injection)to radionuclide P32and I131, and to provideexperimental basis for the targeted radiotherapy of lymph gland in clinical research area.Methods: Nuclide-nano-carbon suspension was prepared by taking the nanometeractive carbon as the carrier and the radionuclide P32and I131as the model nuclide,and thenbe separated so as to detect the adsorption of the nanometer active carbon to radionuclideP32and I131.Results: The adsorption rate of nanometer active carbon to radionuclide P32is0.006mCi/mg, and that to radionuclide I131is0.04mCi/mg.Conclusion: Nanometer active carbon (Carbon Nanoparticles Suspension Injection) can absorbthe radionuclide P32and I131,,but the adsorption rate is relatively low. Only with physical absorption, itcan not carry enough radionuclide P32or I131to conduct targeted radiotherapy to the regional lymphnodes.
