Embodiment Construction

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0043] K gold (or karat gold) is an alloy made of gold and other metals. K gold jewelry is characterized by less gold consumption, low cost, and can be formulated into various colors, and has increased hardness, which is not easy to deform and wear. K gold is divided into 24K gold, 22K gold, 18K gold and 9K gold according to the gold content.

[0044] With the continuous development of the precious metal industry, people's demand for K gold jewelry continues to increase, and the demand for testing the gold content in K...

Abstract

The invention discloses a low-purity gold quantitative detection method which is improved on the basis of a national standard fire assay method, and the gold content of a to-be-detected sample is increased by adding standard gold into the to-be-detected sample, so that the gold content of to-be-detected metal meets the detection range of the detection method. Furthermore, the low-purity gold can be quantitatively detected by using a method for detecting the gold content of the GB / T 9288-2019 gold alloy jewelry.

Description

technical field [0001] The present application relates to the technical field of detection of K-gold element content in jewelry, in particular to a quantitative detection method for low-purity gold. Background technique [0002] K gold (or karat gold) is an alloy made of gold and other metals. K gold jewelry is characterized by less gold consumption, low cost, and can be formulated into various colors, and has increased hardness, which is not easy to deform and wear. According to the current national standard GB 11887, gold alloy jewelry can be divided into pure gold, 22K gold, 18K gold, 14K gold and 9K gold according to the purity. [0003] With the continuous development of the precious metal industry, people's demand for K gold jewelry continues to increase, and the demand for testing the gold content in K gold jewelry is also increasing. The current detection method for gold content in gold alloy jewelry is GB / T 9288-2019 When the detection range of this detection meth...
