中文名称:橡胶.总硫含量的测定.第2部分:过氧化钠熔化法
英文名称:Rubber — Determination of total sulfur content — Part 2: Sodium peroxide fusion method
发布日期:1992-07
标准范围
适用于NR、CR、SBR、BR、IR、IIR、EPDM、NBR和硬质橡胶(见ISO 1629)。该方法的原理是用过氧化钠氧化,将硫转化为硫酸根离子,并通过重量分析测定硫酸钡。本方法适用于测定橡胶或橡胶制品中的所有硫,包括可用作填料的硫酸钡中的硫。
Is applicable to NR, CR, SBR, BR, IR, IIR, EPDM, NBR, and ebonite (see ISO 1629). The principle of the method is oxidation with sodium peroxide, conversion of sulfur to sulfate ions, and determination of the sulfate by gravimetric analysis as barium sulfate. The method is applicable for the determination of all the sulfur present in a rubber or rubber product, including that contained in barium sulfate which may be used as a filler.
