| 摘 要： | 应用高频红外碳硫分析仪测定土壤、粘土中的硫含量,对助熔剂的选择、分析时间、吹氧流量及称样量等分析条件进行优化后对标准样品中的硫含量进行测定,测定结果均在标准值范围内。土壤样品测定结果的相对标准偏差为5.10%(n=8),粘土样品测定结果的相对标准偏差为5.51%(n=8)。该方法对实际样品的测定结果与硫酸钡重量法测定结果相吻合。

| Abstract: | Determination of sulfur in soils and clays by high frequency infrared absorption spectrometry was introudced.The analytical conditions such as assist melting agents and flow capacity of sweeping oxygen were selected,and analytical time and sampling weight etc were discussed in detail.The results of sulfur content measurement of two reference materials were in a nominal value range and the parallel relative standard deviations of eight samples soils were less than 5.10% and clays were less than 5.51%.The results determined by the method were insistent with those determined by the barium sulfate gravimetric method. |
