Abstract—

We have developed and tested a technique for total carbon determination in small sulfur samples (0.1–1.5 g), as well as in volatile and nonvolatile impurities in sulfur. The technique involves IR-spectroscopic determination of carbon dioxide resulting from the oxidation of a sulfur sample and the nonvolatile residue or gaseous impurities with copper(II) oxide. The detection limit of the technique for carbon is 0.3–1.5 μg, and the error of determination is 20%. We have determined the percentage of carbon in sulfur samples of various origins and in volatile and nonvolatile impurities in the samples.

硫和挥发性和非挥发性硫蒸馏馏分的碳含量

摘要——

我们开发并测试了一种用于测定小硫样品 (0.1–1.5 g) 以及硫中挥发性和非挥发性杂质的总碳含量的技术。该技术涉及对硫样品氧化产生的二氧化碳和非挥发性残留物或气态杂质与氧化铜 (II) 进行红外光谱测定。该技术对碳的检出限为0.3-1.5 μg，测定误差为20%。我们已经确定了各种来源的硫样品以及样品中挥发性和非挥发性杂质中碳的百分比。
