Announcement of four industry standards such as "methods for chemical analysis of strontium ores-part 1: determination of strontium, barium, calcium, magnesium, iron and aluminum content-mixed flux semi-melting-inductively coupled plasma atomic emission sp

The Ministry of Natural Resources announced that the four recommended industry standards, such as "methods for chemical analysis of strontium ores, part 1: determination of strontium, barium, calcium, magnesium, iron and aluminum content mixed flux semi-melting-inductively coupled plasma atomic emission spectrometry", have been examined by the National Natural Resources and Land Space Planning Standardization Technical Committee, and are now approved and promulgated, and will be implemented from May 1, 2022. The standard number and name are as follows:

DZ/T 0393.1-2021

"methods for chemical analysis of strontium ores-part 1: determination of strontium, barium, calcium, magnesium, iron and aluminum content-mixed flux semi-melting-inductively coupled plasma atomic emission spectrometry"

DZ/T 0393.2-2021

Methods for chemical analysis of strontium ores-part 2: determination of sulfur content-mixed flux semi-melting-barium sulfate gravimetric method

DZ/T 0393.3-2021

"methods for chemical analysis of strontium ores-part 3: determination of aluminum, calcium, iron, potassium, magnesium, sodium, phosphorus and titanium content-mixed acid decomposition-inductively coupled plasma atomic emission spectrometry"

DZ/T 0393.4-2021

"methods for chemical analysis of strontium ores-part 4: determination of chromium, copper, manganese, molybdenum, nickel, lead, titanium and zinc content-closed acid solution-inductively coupled plasma mass spectrometry"
