Ammonium perrhenate analysis
Thread Content
Which friend has an analysis method for ammonium perrhenate? Could we exchange ideas and learn from each other?
After searching online, the main standards related to this topic are as follows: YS/T 894-2013 “Ammonium perrhenate”; YS/T 902-2013 “Chemical analysis methods for high-purity rhenium and ammonium perrhenate – Determination of amounts of beryllium, sodium, magnesium, aluminum, potassium, calcium, titanium, chromium, manganese, iron, cobalt, nickel, copper, zinc, arsenic, molybdenum, cadmium, indium, tin, antimony, barium, tungsten, platinum, thallium, lead, and bismuth – Inductively coupled plasma mass spectrometry”; YS/T 833-2012 “Chemical analysis methods for ammonium perrhenate – Determination of amounts of beryllium, magnesium, aluminum, potassium, calcium, titanium, chromium, manganese, iron, cobalt, copper, zinc, and molybdenum in ammonium perrhenate – Inductively coupled plasma atomic emission spectrometry”; YS/T 895-2013 “Industry standard for non-ferrous metals of the People’s Republic of China: Chemical analysis methods for high-purity rhenium – Determination of trace impurity elements – Glow discharge mass spectrometry”. However, no free electronic versions were found; if the original poster needs them, they can purchase them separately
Which marine friend has an analytical method for the intermediate stages of ammonium perrhenate production? What are the analysis methods for the ammonium perrhenate content in samples such as sediment residues, extraction solutions, and back-extraction solutions? The intermediate sample has more interference from product impurities
