水合五氧化二锑的合成及其对Sc^(3+)吸附性能的研究

STUDIES ON THE SYNTHESIS AND ADSORPTION PROPERTIES OF HYDRATEDANTIMONY PENTOXIDE

利用所合成的水合五氧化二锑（HAP），研究了它对Sc(3+)及其他离子的吸附性能,结果表明，所合成的HAP在酸性条件下不仅能吸叫Na+．而且对Sc(3+)也有很好的吸附性能.此外.还测定了所合成的HAP在不同烘烤温度下的晶胞参数及对Sc(3+)的吸附交换性能，实验表明经250℃烘烤的HAP具有对Sc(3+)最大的吸附交换容量．

Hydrated antimony pentoxide (HAP) was synthesized and its adsorptionpropertieswere discussed. It showed that HAP synthesized can absorb Na+ and Sc3+ well under acidicconditions. X-ray diffraction was used to determine the structure of HAP, which showed acubic structure with the lattice parameter 1.037 nm. Observations on adsorption properrties ofHAP synthesize at different temperature showed 250℃ is the favorite.
