磷酸－氢钛二水合物的合成和性能表征

Study on the Synthesis and Characteristics for Titanium monhydrogenphosphate Hydro Compound

该文合成了一种具有层状结构的磷酸－氢钛二水合物（Ｔｉ（ＨＰＯ４）２２Ｈ２Ｏ）（记为γ－ＴｉＰ），并对该化合物的性能进行了多种表征．实验证明：它是一具有独特性能的无机离子交换体，对氨的吸附性能与价格昂贵的磷酸－氢锆一水合物（Ｚｒ（ＨＰＯ４）２Ｈ２Ｏ）（α－ＺｒＰ）相当。

A titanium monhydrogenphosphate hydro compound (Ti(HPO 4) 2·2H 2O) (γ TiP) with layered structure has been synthesized,measured and characterized by x ray,TG and DTA.It is an inorganic ion exchanger with excellent properties and adsorp speedity and efficiently ammonian (aqueous or gas).It is similar to the absorpability of titanium monhydrogenphosphate hydro compound (Ti(HPO 4) 2·2H 2O) and the zirconium monhydrogenphosphate hydro compound (Zr(HPO 4) 2·H 2O) (α ZrP) on ammonian,but the latter is expensive.
