针对Sb（Ⅲ）-HCl-H2O体系,应用热力学计算方法,根据同时平衡原理,建立了数学模型,以Sb（Ⅲ）的总浓度5×10-5 mol/L为例,计算了不同pH时Sb（Ⅲ）的各种存在形式的浓度分布.计算结果表明,pH=1.3～4.0时,SbO＋是主要存在形式,且n（SbO＋）/n（Sb总）〉99.8%.

The concentration distributions of various existing forms of Sb(Ⅲ) in Sb(Ⅲ)-HCl-H2O system were calculated by building a thermodynamic calculation model according to the principle of simultaneous reaction equilibrium,based on assumptions of the total content 5×10-5 mol/L of Sb(Ⅲ) in different pH in this system.The results indicate that SbO+ is the mainly existing form of Sb(III),n(SbO +) / n(Sbtotal)99.8% while 1.30pH4.
