Pb2+吸附水钠锰矿锰氧化度八面体空穴研究水钠锰矿对重金属离子的吸附,其结构中八面体空穴特点与重金属离子吸附的关系是人们关注的热点.采用酸性和碱性2种介质条件合成了具有不同锰氧化度的2个系列水钠锰矿,研究了它们的锰氧化度(average oxidation state of Mn, AOS)与其d110面网间距和Pb2+的最大吸附量的关系...
研究水钠锰矿对重金属离子的吸附,其结构中八面体空穴特点与重金属离子吸附的关系是人们关注的热点.采用酸性和碱性2种介质条件合成了具有不同锰氧化度的2个系列水钠锰矿,研究了它们的锰氧化度(average oxidation state of Mn, AOS)与其d110面网间距和Pb2+的最大吸附量的关系,以及Pb2+吸附量与Mn2+,H+和K+释放...
aChemical composition (obtained by ICP), average oxidation state of manganese (AOS) (obtained by H2-TPR), percentage of Ce(III) on the surface and oxygen vacancies (obtained bystudying Ce3d and O1s spectra, respectively, Fig. 4 and Table S2). ICP (、锰AOS)平均铈III的氧化态 (获得) (...
A magnetic route has been applied for measurement of the average oxidation state (AOS) of mixed-valent manganese in manganese oxide octahedral molecular sieves (OMS). The method gives AOS measurement results in good agreement with titration methods. A maximum analysis deviation error of +/-7% is...
