Abstract
A methodology of quantitative determination of cobalt using the PIXE method has been developed. The method is based on the use of instant nuclear-physical analysis with the inducement of a target by a 1.6 MeV proton beam and the recording of the characteristic X-ray emission of the K-series of the cobalt. The linear relationship between the quantitative content of cobalt strontium and its X-ray emission K-shell was obtained. The sorption of cobalt by natural and synthetic zeolites from aqueous solutions in dynamic conditions has been studied. Sorption of cobalt with clinoptilolite after 80 cycles of sorption was about 60%. Sorption of cobalt after 80 cycles of sorption by zeolites NaX and NaA was 86 and 70%. Consideration was given to the influence of competing ions (sodium) on the sorption of cobalt by zeolites. The introduction of competing ions leads to a decrease in sorption of the cobalt by 25–60%, depending on the content of competing ions.
