摘　　要：利用人工合成的 1nm锰矿相与铜、钴、镍等二价金属阳离子的离子交换实验的结果表明 :人工合成 1nm锰矿相具有强烈的金属阳离子交换能力 ,其交换能力大小顺序为Cu2 +>Co2 +>Zn2 +>Ni2 +;有机质存在对离子交换起到抑制作用 .阳离子交换是多金属结核成矿后期的重要途径 .从镍离子较弱的交换能力和其在结核中较高含量的矛盾中可推测 :铜、钴、镍等有价金属元素在多金属结核中的富集 。The substitution experimental of Cu,Co,Ni cations into synthetic 1nm manganate show that S1nm manganate has the strong ability of exchanging the transition cations. The preference substitution order is: Cu>Co>Zn>Ni. The cations substitution is the important mechanism of the enrichment of the valuable metal elements such as Cu,Co and Ni in the polymetallic nodules. It is found that the organic matter would weaken this substitution. According to the weak substitution ability and the high content in the nodules for Ni, It is possible that the enrichment of Cu,Co,Ni elements in the polymetallic nodules is the multielements result of biological and chemical mineralization, etc.
