batteries, in the form of metal oxides nanoparticles [1,2]. Cobalt is one of the main metal constituents of LIBs cathode material and therefore, the recovery of cobalt oxide precursors and investigation of their decomposition reaction mechanism have great importance from the economic viewpoint as well as environmental aspects. Cobalt oxide has been widely used in heterogeneous catalysis, electrochromic......
addition on iron removal rate and cobalt loss rate 由图1可知,除铁率和钴损失率都随着双氧水用量的增大而显著升高.当双氧水用量由理论量的0.6倍提高至1.5倍时,除铁率由52.01%上升至99.68%,此后继续增大双氧水用量至理论量的2倍,除铁率微升至99.72%.溶液的钴损失率在0.6倍双氧水理论用量时为0.96%,在1.5倍理论用量时升至2.87%,继续增大...; Influence of pH value of solution final solution on iron removal rate and cobalt loss rate 2.2~4.1间迅速增加.在pH为1.5和2.6时,钴损失率分别为1.86%和2.87%,进一步升高pH至4.1时,钴损失率升至4%.因此,从除铁率,钴损失率及中和剂消耗量等方面综合考虑,选择合适的pH值为2.6. 2.1.3......
