摘要
通过特殊设计的海-空交换模型实验表明,海水中Zn^(2+)等痕量金属离子,可全浓度随水蒸发循环。自由能ΔG^(0)不足以直接判断这个痕量浓度物理-化学过程进行的可能性,热力学出现反常。
The experimental results show that,when the water is evaporated,the trace metal ions Zn^(2+)etc.contained in this water can transfer in 100%concentration to water vapor under the limiting concentration of transfer.Therefore,the free energy,△G^(0),can not be used directly to predict the feasibility of this trace concentration physico-chemical process.The anomaly of thermodynamics in trace concentration physico-chemical system is presented as an experimental fact.
