Foreword

YS/T 34 "high-purity arsenic chemical analysis method" consists of three parts. --- Part 1. Methods for chemical analysis of high-purity arsenic by inductively coupled plasma mass spectrometry (ICP-MS) Determination of impurities in high-purity arsenic content; --- Part 2. Determination of the amount of high-purity arsenic and selenium chemical analysis of polarography; --- Part 3. Determination of the amount of high-purity arsenic and sulfur chemical analysis of polarography. This section is YS/T Part 1 34. The partial replacement of YS/T 34.1-1992 "Methods for chemical analysis of high purity arsenic malachite green spectrophotometric determination of antimony content" and YS/T 34.2- 1992 "Methods for chemical analysis of high-purity arsenic chemistry spectrometry determination of cobalt, zinc, silver, copper, calcium, aluminum, nickel, chromium, lead, magnesium, iron." This section compared with YS/T 34.1 ~ 34.2-1992 standard, there are the following changes. Determination of arsenic in high purity magnesium, chromium, nickel, copper, zinc, silver, lead, bismuth, sodium, potassium, aluminum, calcium, iron, antimony --- using inductively coupled plasma mass spectrometry, etc. Content of 14 impurities. --- According to GB/T 1.1-2009. the preparation of "Standardization Guide Part 1 standard structure and writing" requirement.

1 Scope

YS/T of the provisions of section 34 of the method for the determination of arsenic in high purity metallic impurities, using inductively coupled plasma mass spectrometry determination of arsenic Magnesium, chromium, nickel, copper, zinc, silver, antimony, lead, bismuth, sodium, potassium, aluminum, calcium, iron and other impurities 14. This section applies to the determination of 99.99999% ~ 99.999% high-purity arsenic content of metal impurities. Determination range of 1 × 10-7% ~ 1000 × 10-7%.

2 Method summary

Under the conditions of 120 ℃ ~ 130 ℃, the sample with hydrogen chloride - chlorine gas mixture reacts and impurity elements arsenic trichloride chloride, low After boiling volatile with arsenic trichloride gas flow, dissolved in nitric acid chloride impurities left behind.
