Scope

Main technical content: This document specifies the test method for determining the iron and arsenic content in industrial sulfur using inductively coupled plasma emission spectrometry. This document is applicable to the determination of iron and arsenic content in industrial sulfur. The determination range of iron is 0.05 mg/kg to 500 mg/kg, and the determination range of arsenic is 0.05 mg/kg to 100 mg/kg. This method can also be used to determine the content of elements beyond this range, but the precision has not been investigated
