- Scope
- This document specifies the test method for the determination of iron and arsenic content in industrial sulfur using inductively coupled plasma optical emission spectrometry. This document is applicable to the determination of iron and arsenic content in industrial sulfur. The determination range of iron element is 0.05mg/kg~500mg/kg, and the determination range of arsenic element is 0.05mg/kg~100mg/kg. This method can also be used for determination beyond this range, but the precision has not been tested.
