Possible Interaction: Cobalt and Manganese

“In the metal-on-metal group, concentrations of … increased significantly when compared with preoperative values: cobalt , 15.3-fold (95% confidence interval [CI], 9.4-21.2); chromium, 5.2-….5-7.0); nickel, 2.1-fold (CI, 1.2-3.0); and manganese , 1.6-fold (…-2.0).”

“Moreover, the muscle content of iron and manganese showed an inverse relationship with the dietary Co supplementation.”

“Although the extent of reactivation by these two metal ions was almost similar, cobalt required a ten times lower concentration than manganese for this process.”

“However, while manganese inhibited slightly (17%), neither cobalt nor cadmium had effect in this concentration range.”

“Interestingly, the synergy between cobalt and manganese species in the cobalt manganese phosphate thin film electrode demonstrates a maximum specific capacitance of 571 F g-1 at a 2.2 A g-1 current density in 1 M KOH.”

“… cobalt ions partially replace … of the manganese ions, and the emergence of Co3+ ions is inferred to induce the formation of a built-in electric field in the … enhance the electrochemical behaviour of MnV2O6, presenting a high capacity of 1005.9 mA h g-1 after hundreds of cycles.”

“We observe that metallic manganese alloyed with polycrystalline cobalt promotes the dissociation of CO.”

“The excellent properties mainly related to its higher specific surface area and abundant active sites originated from hollow microsphere special structure consists of abundant nanosheets, robust redox properties beneficial for the strong interaction between the manganese and cobalt , larger number of acidic sites and stronger acid strength, etc.,”

“Moreover, both single and combined treatments of Co and Cu reduced the mineral ( Mn , Zn and K) uptake.”

“ Manganese oxides are important environmental oxidants that control the fate of many organic and inorganic species including cobalt.”
