| 中文摘要: |
| 报道了在室温下钾与负氢混合物中钾钙发生嬗变的现象，负氢是由NaBH4、LiBH4和NH3BH3提供的.实验中的钾和钙的浓度分别用诱导耦合等离子发射光谱法（ICP-OES）和诱导耦合等离子质谱法（ICP-MS）进行检测.ICP-OES结果表明随着混合物中钾浓度的降低伴随着钙的浓度增加.此外ICP-MS结果还表明40Ca浓度的增加伴随着41K浓度的增加，可能表明在负氢存在的条件下混合物中40Ca的生成与41K物种有关. |
| 英文摘要: |
| Here, we report the transmutation of K-Ca under the negative hydrogen condition (NaBH4, LiBH4 and NH3BH3) at room temperature. In all reaction systems, the amount of K+ and Ca2+ concentrations were monitored by inductive coupled plasma optical emission spectroscopy (ICP-OES) and inductive coupled plasma mass spectrometry (ICP-MS) techniques. The ICP-OES test results showed that K+ concentration was gradually decreasing, while the Ca2+ concentration was gradually increasing. In addition, by comparing the K and Ca concentrations and their isotopes from the ICP-MS results, we found the increase of 40Ca concentration accompanied by the increasing concentration of 41K in the presence of hydride under our "reaction" conditions, which implying 40Ca formation correlated to 41K. |
