        In this study, a new type of composite material combined with carbonyl iron, a relatively strong ferromagnetic material, was prepared to overcome the current application limitations of Prussian blue, which is effective in removing radioactive cesium. The surface of the prepared composite was analyzed using SEM and XRD, and it was confirmed that nano-sized Prussian Blue was synthesized on the particle surface. In order to evaluate the cesium removal ability, 0.2 g of the composite prepared for raw cesium aquatic solution at a concentration of 5 μg was added and reacted, resulting in a cesium removal rate of 99.5 %. The complex follows Langmuir’s adsorption model and has a maximum adsorption amount (qe) of 79.3 mg/g. The Central Composite Design (CCD) of the Response Surface Method (RSM) was used to derive the optimal application conditions of the prepared composite. The optimal application conditions achieved using Response optimization appeared at a stirring speed of pH 7, 17.6 RPM. The composite manufactured through this research is a material that overcomes the Prussian Blue limit in powder form and is considered to be excellent economically and environmentally when applied to a cesium removal site.

        “Guang jiao chou lue” (《廣校讎略》), an early masterpiece by Professor Zhang Shunhui (張舜徽) (1911-1992), has a significant impact on the theory system of Philology. It adopts widely the pre-existing discussions, which makes it have great historical significance inheriting the past and opening future. Jiao Chou Xue (《校讎學》) is one Textualism theory works by Xiang Zonglu (向宗魯) (1895-1941), which is completed earlier, be a system, both theoretical and practical.It reflects the author’s objections to the idea of “Jiaochou” (校讎).
