采用库仑滴定法测定铁矿石中的硫含量 ,利用智能测硫仪 ,在催化剂作用下 ,使铁矿石中的硫在高温下以SO2 形式释放出来 ,用电解生成的碘滴定H2 SO3,该方法准确度好 ,测量范围宽。
The Coulometric titration method was used to determine the sulfur content in iron ore. Using the smart sulfur measuring instrument, the sulfur in iron ore was released as SO2 at high temperature under the action of the catalyst. The iodine generated by electrolysis was titrated with H2 SO3 Method accuracy, wide measuring range.
