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 second part of the SN/T 4501. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part is proposed and managed by the National Certification and Accreditation Administration.

3 Principle of the method

The sample was digested with nitric acid, hydrochloric acid, hydrofluoric acid and hydrogen peroxide by a closed microwave, and the salt was dissolved with nitric acid. Inductive coupling after sample processing Determined by a plasma mass spectrometer. The standard curve is quantified by internal standard method.
