摘　　要：1引言近年来，我国人造金刚石的产量和应用有了很大的发展。以现有的人造金刚石合成技术，通常以Fe，Ni，Co，Mn等元素组成的合金作为触媒，这使人造金刚石中极易残留这些金属组成的包裹体。诸多研究表明，A method for the determination of Fe, Co, Mn and Ni in synthetic diamonds by inductively coupled plasma atomic emission spectrometry （ICP-AES） was proposed. The synthetic diamond sample was decomposed completely, while the sample was burned in air at 1000 ℃ for 10 h, and then a mixed acid of H2SO4, aqua regia and HC104 was used for the dissolving the residue of the sample. In this method, the limits of detection of Fe, Co, Mn and Ni were 0. 0147, 0. 0018, 0. 0006 and 0. 0027 mg/L, respectively. Under the optimum condition, Fe, Co, Mn and Ni in Synthetic diamond sample were determined. The values of RSDs （n = 7） were less than 0.5%, The recoveries of added standard were 94.0%-105.0%.
