Abstract
Different molar ratios of the cerium trichloride heptahydrate to isopropyl alcohol (1:2, 1:3 and 1:5) were studied
to choose the optimum ratio, and studied the reaction temperature effect (80, 90 and 100 �C) to determine the
optimum temperature for the preparation of poly nano cerium chloride (PNCC). The PNCC-1 was selected among
the prepared PNCC batches based on the 99Mo sorption properties that confirms the feasibility of using it as a
novel effective sorbent material. The structural properties and chemical composition were studied using different
techniques and devices such as EDX, XRD, FESEM, FTIR, TGA, and DTA. The sorption capacity was found to be
450 � 27 and 195 � 11 mg/g PNCC-1 using the static and dynamic techniques, from 0.01 M NaOH to obtain
about 55 and 75% 99mTc separation efficiency, respectively. The acceptability of the eluate 99mTc was investigated from the point of view of radiochemical, radionuclidic and chemical purity.
