Introduction

GB/T 11066-2009 "Gold Chemical Analysis Method" has been implemented for more than 10 years. With the revision of the product standard "Gold Ingot", the new The product standard GB/T 4134-2015 has already been released and will be implemented on April 1,.2016.GB/T 4134-2015 "Gold Ingot" standard The required elements have also changed. Therefore, the gold chemical analysis method GB/T 11066-2009 needs to be improved. In recent years, testing new technologies Hexin instruments have also developed rapidly, and the instruments of various gold production and processing enterprises, research units and third-party testing units have also been updated quickly. The stations are basically equipped with inductively coupled plasma mass spectrometry (ICP-MS), one of the most advanced inorganic element analysis technologies in the world. versus The formulation of accurate, fast, advanced and efficient standard analytical methods for gold production and application is urgently needed. This document is the 11th part of GB/T 11066 "Gold Chemical Analysis Methods". It uses inductively coupled plasma mass spectrometry technology to achieve gold The determination of the content of magnesium, chromium, manganese, iron, nickel, copper, palladium, silver, tin, antimony, lead, and bismuth is a new application of new technology in the chemical analysis of gold. This part is The above 10 parts are supplemented by accurate, direct and effective detection methods of trace and trace impurity elements in gold, which are traceable and can be used as The arbitration method for the detection of trace and trace amounts of magnesium, chromium, manganese, iron, nickel, copper, palladium, silver, tin, antimony, lead, and bismuth in gold. Gold chemical analysis method Part 11.Magnesium, Chromium, Manganese, Iron, Nickel, Copper, Palladium, Silver, Determination of tin, antimony, lead and bismuth content Inductively coupled plasma mass spectrometry Warning---The personnel using this document should have practical experience in formal laboratory work. This document does not indicate all possible safety issues question. The user is responsible for taking appropriate safety and health measures and ensuring compliance with the conditions stipulated by relevant national laws and regulations.
