摘　　要：主要研发一种基于酸碱库仑滴定技术的新型库仑定硫仪,其性能远优于目前大量使用的基于碘量法的库仑定硫仪,可以实现高温燃烧酸碱滴定测定煤中全硫方法的仪器化和自动化。该仪器适用于测定煤、土壤、沉积物和各种地质样品的全硫含量。This paper mainly develops a new coulomb sulfur determination instrument based on acid-base coulomb titration technology.Its performance is much better than that of the coulomb sulfur meter based on iodimetry, which is widely used at present. The instrument is suitable for the determination of total sulfur content of coal, soil, sediment and various geological samples.
