In order to study the organic affinity of trace elements in coal from No.10 coal-bed at western Huagou, Guoyang, 10 borehole samples were collected at exploration area of Huaibei mining area. The contents of 12 kinds of trace elements were determined by the inductively coupled plasma mass spectrometry (ICP-MS), the total organic carbon (TOC) of coal was determined by LECO carbon and sulfur analyzer, and the organic affinity of trace elements were deduced from the correlations between contents and TOCs. The results showed that the contents of V, Cr, Co, Ni, Mo, Cd, Sb, Pb and Zn were lower than the average of Chinese coal and weren’t anomalously enriched, and Be, Cu and Tl were slightly higher. Cd had a strong organic affinity, organic affinity of Co, Zn, Be and Cr was weaker than that of Cd, but V, Ni, Cu, Mo, Sb, Pb and Tl did not have inorganic affinity.
