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.

研究七水合七水合铈与异丙醇的不同摩尔比（1：2、1：3和1：5）以选择最佳比例，并研究反应温度效应（80、90和100°C）确定制备聚纳米氯化铈（PNCC）的最佳温度。根据⁹⁹ Mo的吸附特性，从制备的PNCC批次中选择PNCC-1 ，这证实了将其用作新型有效吸附材料的可行性。使用不同的技术和设备（例如EDX，XRD，FESEM，FTIR，TGA和DTA）研究了结构特性和化学成分。使用静态和动态技术，从0.01 M NaOH获得约55％和75％的^99m吸附力，发现PNCC-1的吸附容量为450±27和195±11 mg / g PNCC-1。Tc分离效率分别。从放射化学，放射性核素和化学纯度的角度研究了洗脱液^99m Tc的可接受性。
