用燃烧中和法测定黄铁矿中硫含量是一简捷的方法,但也存在一些问题有待以研究。第一,硫转化率低是一个普遍性问题。不少资料用补正值来解决,而未涉及到,样品内部矛盾,实际上关系到矿物中硫的赋存状态,硫酸盐越高则转化率越低。燃烧法定硫如果采用理论值计算势必形成系统偏低。为此必须以标样来标定滴定液。第二,国内外介绍 Determination of sulfur content in pyrite by combustion neutralization method is a simple and convenient method, but there are some problems to be studied. First, low sulfur conversion is a common problem. A lot of information to use correction values ​​to solve, but not involved, the sample internal conflicts, in fact, relates to the occurrence of sulfur in the mineral state, the higher the sulfate conversion rate is lower. If you use the theoretical value of burning sulfur combustion is bound to form the system is low. To this end, the standard must be used to calibrate the titrant. Second, introduction at home and abroad
