摘要: 采用共沉淀法制备了纳米硫化铜颗粒，采用溶解度法分别测定了纳米硫化铜和对应块体硫化铜在288.15 K、298.15 K、308.15 K、318.15 K、328.15 K时的溶液平衡常数，依据溶解热力学理论进一步计算了硫化铜的溶解热力学函数，通过与块体对比进一步获取了硫化铜的表面热力学函数。
Abstract: Nanocrystalline copper sulphide particles were prepared by coprecipitation method. The solution equilibrium constants of nanometer copper sulfide and corresponding bulk copper sulfide at 288.15 K, 298.15 K, 308.15 K, 318.15 K, 328.15 K were determined by solubility method. Based on the theory of dissolution thermodynamics, the dissolution thermodynamic function of copper sulfide was further calculated, and the surface thermodynamic function of copper sulfide was obtained by comparison with bulk.
