ELEMENT PARTITION COEFFICIENTS IN MELT-SOLUTION SYSTEMS: NEW DATA AND FUTURE RESEARCH TRENDS

基于近几年来国内外学者测得的熔体-溶液体系中F、Cl、P、CO_2、B、Au、Pb、Zn、Cu、Fe、Mg、Li、Rb、Cs、K、Na、Ca、Sr、Ba、Co、Ni、Be、Mo、W、Si、Al、REE、Sc、Ti、U、Th、Zr、Hf、Nb、Pt、Ir、Pd等元素的分配系数,从元素性质、溶液成分(阴离子和阳离子)、熔体成分和物理化学条件等方面进一步分析总结了分配系数变化规律,并提出了预测未知元素分配系数的元素性质准则、溶液成分准则、熔体成分准则和物理化学条件准则,最后指出了这一研究领域今后的研究方向。

Melt-solution element partition coefficients help reveal the behavior regularities of elements in the process of melt-solution interaction. Based on the partition coefficient data of F, Cl, P, CO2, B, Au, Pb, Zn, Cu, Fe, Mg, Li, Rb, Cs, K, Na, Ca, Sr, Ba, Co, Ni, Be, Mo, W, Si, Al, REE, Sc, Ti, U, Th, Zr, Hf, Nb, Pt, Ir, Pd, experimentally determined by a lot of researchers in recent years, further variation regularities of element partition coefficients ate discussed in terms of element nature, melt composition, solution composition and physico-chemical parameters. Four corresponding criteria for the prediction of unknown element partition coefficients are proposed. Finally, the trends of this research field are pointed out.
