Foreword

SN/T 4501 "Chemical Analysis Method for Nickel Concentrate" is divided into three parts. ---Part 1. Determination of the content of nickel, cobalt, copper, manganese, magnesium and calcium - Inductively coupled plasma atomic emission spectrometry; --- Part 2. Determination of gallium, antimony, selenium, cadmium, indium, antimony, antimony and bismuth content by inductively coupled plasma mass spectrometry; ---Part 3. Determination of gold, platinum and palladium content by inductively coupled plasma mass spectrometry. This part is the third part of the SN/T 4501. This part is drafted in accordance with the provisions given in GB/T 1.1-2009. This part is proposed and managed by the National Certification and Accreditation Administration. This section is mainly drafted by. Gansu Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, Jinchuan Group Co., Ltd. The main drafters of this section.

3 Principle

The sample and the mixed flux are mixed in proportion, and melted at a high temperature to obtain a precious metal granule, which is sequentially dissolved by dissolving precious metal with nitric acid and aqua regia. A solution of gold, platinum, or palladium. Determination of the signal value of an element in the above solution by inductively coupled plasma mass spectrometry (ICP-MS) using an internal standard Method of quantification. The concentration of the element in the solution is proportional to the signal value of the instrument within the measurement range of the element.
