有机质对S1nm锰矿相金属阳离子交换能力的影响
Organic matter effect on the cation substitution capacity of synthetic 1nm manganate
-
摘要: 大洋多金属结核问题长期以来一直受到人们的关注[1~3].大量的研究结果表明,多金属结核中最有经济价值的铜、钴、镍等有价金属元素,主要赋存于仅占整个结核约15%锰矿相中.我们曾对人工合成1 nm锰矿相(synthetic 1nm manganate,以下简称S1nm锰矿相)金属阳离子交换能力作过初步探讨[4,5],研究表明,Cu2+,Co2+,Ni2+,Zn2+等与S1nm锰矿相具有强烈的阳离子交换能力,证明了多金属结核成矿后期的离子交换是铜、钴、镍、锌等有价金属元素进入多金属结核的重要途径之一.
