摘要

本文研究無機離子交換劑，金屬氫氧化物，銅(II)，鈰(III)，鈷(III)，鉻(III)，鐵(III)，錳(IV)，鋯(IV)，鈦(IV)，錫(IV)，鎳(IV)，鈰(IV) ，及磷酸鋯，磷酸鈰， 矽酸鋯等14種之合成方法。並探討其交換性質，各種交換劑對陰陽兩離子之吸着容量；化學安定性如耐酸耐鹼度之測定；分析金屬氫氧化物交換劑以明瞭其組成；觀察交換劑之含水量與吸着容量之關係；同時選出數種吸着容量較大之交換劑，試驗乾燥溫度及pH之變化對其吸着容量之影響，結果發現兩種新無機離子交換劑，氫氧化鈰及矽酸鋯，交換容量頗大，前者在pH值12.45時為，5.2meq/g，後者在pH值12.55時為3.18 meq/g，且具有在酸性溶液中亦有吸着能力之優點。

In this article are presented the chemical synthetic methods for 14 inorganic ion exchangers such as hydrous oxides of Cu(ll), Ce(III ), Co(lll), Cr (III ), Fe(III), Mn(IV), Zr(IV), Ti(IV), Sn(IV), Ni(IV) and Ce(IV), and acid salts of zirconium phosphate, zirconium silicate, and cerium phosphate. The ion exchanger properties, chemical stability, anion and cation adsorption capacities of these compounds, were observed. Several anion and cation exchangers, having high adsorption capacity, have been selected to study the effects of drying temperature and pH value on adsorption capacity. As a results, it was found that hydrous cerie oxids and zirconium silicate show excellent exchange properties, high adsorption capacity, and acid stability. Their total capacities amount to 5.21 meq/g at pH 12.45 and 3.18 meq/g at pH 12.55.
