摘要： 本文研究了TbO2·xH2O在HCl、HNO3、HClO4和HAc中的存在状态,通过对其光学性质、电学性质、聚沉值的研究,证实TbO2·xH2O在这些酸中均以带正电荷的胶体状态存在.对所得胶体的紫外-可见吸收光谱及溶胶中Tb(Ⅳ)水合氧化物的氧化还原动力学进行了研究.

Abstract: In this paper we have studied the existing state of terbium (Ⅳ) oxide hydrate in HCl, HNO3, HClO4 and HAc solutions. Through the investigations of the optical and electrical properties and coagulation values it is showed that the Terbium (Ⅳ) oxide hydrate exists as a sol with positive charges in these solutions. The UVand visible absorption spectra and kinetics of reduction of the sols have also been studied.
