| 摘 要： | 首先从理论上分析了纳米铜在稀酸中溶解的可能性，导出了溶解度与粒度间的热力学关系式；然后测定了不同粒径的纳米铜在稀硫酸中的溶解度，讨论了粒度对纳米铜在稀酸中溶解的影响规律。研究结果表明：粒度对铜在稀酸中的溶解度影响很大；不溶解于稀硫酸中的块状铜，制备成一定粒度的纳米铜后能够溶解于稀酸中，粒度越小溶解度越大；并且纳米铜溶解度的对数与其粒径的倒数呈线性关系；其实验结果与理论分析完全一致。

| Abstract: | The possibility that nano-Cu dissolves in a dilute acid was analyzed theoritically,the thermodynamic relation between the solubility and the particle size of a nano-metal was derived. Besides,it was determined that the solubility of nano-Cu with different sizes in the dilute sulphuric acid,and the effect of particle size on the solubility was discussed.The results show that the particle size of nano-Cu has a considerable influence on the solubility in dilute sulphuric acid;the blocky Cu,which is insoluble in a dilute acid,can dissolve in a dilute acid when turned into nano-Cu with certain sizes, and the smaller the diameter,the higher the solubility,and the logarithm of the solubility has linear relation with the reciprocal of the diameter;and the experiment results are in accordance with the theoretic analysis. |
