中文摘要: 采用高频燃烧红外吸收光谱法测定碳酸钴中的硫,在测定过程中先将样品进行灼烧处理,并选用纯铁和钨助熔剂熔样,解决了水分干扰和样品熔解不完全的问题。方法可以准确测定碳酸钴中质量分数为0.001%~0.01%的硫,加标回收率为98.4%~101.4%,相对标准偏差RSD为2.8%~6.3%。
Abstract:Sulfur in cobalt carbonate samples was determined by infrared absorption spectrometry method with high frequency combustion. In the process of determination, the samples were firstly burned and then melted in pure iron and tungsten fluxing medium. This method solved the problems of moisture interference and incomplete sample melting. The method can accurately determine the sulfur with mass fraction in cobalt carbonate as 0.001%~0.01%.The spiked recovery rates are between 98.4%~101.4% and relative standard deviations are between 2.8%~6.3%.
