In this work we exploited both these approaches simultaneously by forming composites with polyvinyl alcohol, zirconium phosphate and cesium salt of silicotungstic acid.

在本研究中我们通过与聚乙烯醇，磷酸锆，和硅钨酸的铈盐形成复合物，同时探索了这两种方法。

The grafting is believed to take place principally through the active centers which are formed on the cellulose substract by the action of eerie ion.

可以认为，接聚反应的发生主要是通过铈离子与纤维素作用在纤维素上生成活性中心。

Therefore chlorinating cerium dioxide with NH4Cl should strictly control the temperature and time, and over-dose NH4Cl should be applied as well.

因此采用NH4Cl氯化CeO2时，一方面应控制反应温度及反应时间，同时，过量的NH4Cl有利于CeCl3形成。关键词：稀土；铈；氯化；热分解

Methods Soil was air-dried, grinded, and screened through 100 mesh sieve. Appropriate sample was put in porcelain crucible with 0.5 g Aldrin reagents, and another 2 g Aldrin was used to cover the sample. Then the mixture was burned, cooled off, lixiviated by water, and determined by arsenic-cerium redox spectrophotometry.
