摘　　要：利用气相色谱法研究了饱和KCl溶液中十八胺浓度的测定方法。实验表明,在实验所选择的十八胺浓度范围内,以十六烷为内标的标准曲线线性良好,相关系数为0.995 5。测定结果的相对标准偏差为4.5%,回收率为97.7%。说明方法重现性好、准确性较高,适合KCl浮选中饱和KCl溶液中十八胺的测定。The content of octadecylamine in the saturation solution of KC1 was determinated by gas chromatography method. The result indicated that the standard curve had a good linearity with hexadecane as internal standard in a certain concentration range of octadecylamine. The correlation coefficient is 0. 995 5. The relative standard deviation of quantitative analysis method is 4. 52% ,with average recycle ratio 97.7%. Therefore,such method can be used to measure the content of octadecylamine in the KCl saturation solution in KCl flotation with exact repeatability and accuracy.
