中文摘要: 碳酸钴由于受生产工艺的制约,生产的产品组分复杂,且市售碳酸钴产品的命名也存在多样性。本文采用X射线荧光光谱仪、电感耦合等离子体发射光谱仪、元素分析仪、X射线多功能粉末衍射仪和红外光谱仪对某碳酸钴产品的成分进行测定和结构表征。结果表明:该碳酸钴产品钴、碳、氮的含量分别为46.53 %、8.31 %和1.48 %相对标准偏差RSD ≤ 3.31 %(n=6)。研究新发现了N在碳酸钴产品中以NH4+的形式存在,确认该产品为水合碱式碳酸钴铵[(NH4)1.89Co7.88(CO3)6(OH)6(H2O)4.27]和碳酸钴(CoCO3)的混合物。

Abstract:y, For the sake of technique restrictions involved in the cobalt carbonate production, the components of cobalt carbonate products are complicated; moreover, the names of its business products are also diversified. In this paper, the elements of one cobalt carbonate product have been determined and structurally characterized by using X-ray fluorescence spectrometers (XRF), inductively coupled plasma-optical emission spectrometry (ICP-OES), elemental analyzer, Multi-purpose Powder X-ray Diffractometer (XRD) and infrared spectroscopy (IR spectroscopy). The result shows that this product contains 46.53% of cobalt, 8.31% of carbon and 1.48% of nitrogen and the relative standard deviation (RSD) is less than or equal to 3.31% (n=6). The study has newly found that N exists in the form of NH4+ in cobalt carbonate product and this product is confirmed to be the mixture of ammonium cobalt carbonate hydroxide hydrate [(NH4) 1.89 Co7.88 (CO3) 6 (OH) (H2O) 4.27] and cobalt carbonate (CoCO3).
