以金属矿床中有机质的重要组成部分———干酪根为研究对象 ,对干酪根中的Se及其他微量元素进行了分离测定 ,对矿床中元素的有机 /无机结合态进行了定量研究 .认为矿床中Se主要以有机结合态方式存在 ,根据生物化学证据 ,不同成矿演化阶段Se的有机结合态比率以及理论计算和红外光谱分析 ,推断Se可能与有机质中的某些元素键合 ,较为牢固地吸附在有机质中 ,并可能形成Se的有机矿物 .同时 ,也给出了无机结合态硒的可能形式
Taking the kerogen, an important component of organic matter in the metal deposit, as the research object, Se and other trace elements in the kerogen were separated and determined, and the organic / inorganic bound state of the element in the ore deposit was quantitatively studied. Se mainly exists in the form of organic bounds. According to the biochemical evidences, the ratio of organic bounds of Se in different stages of mineralization and theoretical calculations and infrared spectroscopic analysis, it is concluded that Se may bond with some elements in organic matter. Adsorbed in the organic matter, and may form Se organic minerals.At the same time, also given the possible forms of inorganic bound selenium
