| 中文摘要: |
| Synthetic 1nm manganate has been made in the laboratory at low temperature.The d-spacing of which shows 1.002 nm,0.501 nm and 0.34 nm respectively.As the analogue of natural 1nm manganate,it has been used for a series of experiments of divalent canons substitution.The results indicate that the 1nm manganate has very strong canon substitution capacity,which probable is the reason of the valuable metal such as Cu,Ni and Co enriched in the manganese nodules.The preference of canons substituting into S 1nm manganate is Cu > Co > Zn ≥ Ni > Ca > Mg.In the manganese nodules,the content of Ni is usually higher than that of Cu and Co,but in the cation substitution,the latter two are more preference than the former.Cane can infer from this differentiation that the post-deposition canon substitution is not the sole mechanism by which the valuable metals enter the manganese nodules.It could be the resups of combined effects of both original formation and the post-deposition substitution of canons,which leads to the enrichment of valuable metal in the manganese nodules. |
