摘　　要：针对活性炭吸附—碘量法测定地质样品中金的过程可能出现的一些问题进行了探讨,通过实验对试样焙烧、活性炭加入量等影响分析结果准确度的主要因素进行了总结。该方法具有较好的适用性和可操作性,相对标准偏差小于1.12%,回收率达到94.29%～98.86%。The paper discusses the problems in the measuring process of the gold content in geological samples with activated carbon adsorption and iodometry method. The main influencing factors on the measuring accuracy are summarized, such as the roasting process and the dosage of activated carbon. This method has fine applicability and operability. Its relative standard deviation is less than 1. 12% and the recycling ratio is between 94.29 % and 98.86 %.
