形成铁锰结核的胶体-化学性质以及控制这些过程的规律已很清楚,并且已被实验研究和热动力学计算所证实。例如,在较强的氧化环境中,形成具有较强吸附能力的和氧化程度较高的锰的氢氧化物是众所周知的。降低介质中氧化-还原电位和pH值,就会导致氧化程度较低的锰化合物形成。在水分质条件中,形成混合价化合物可能与锰元素氧化程度的变化有
The colloidal-chemical properties of iron-manganese nodules and the rules governing these processes are well established and have been demonstrated by experimental studies and thermodynamic calculations. For example, it is well known to form hydroxides of manganese having a higher adsorption capacity and a higher degree of oxidation in a stronger oxidizing environment. Decreasing the oxidation-reduction potential and pH in the medium results in the formation of manganese compounds with a lower degree of oxidation. In the water quality conditions, the formation of mixed valence compounds may be the degree of oxidation with manganese change
