Introduction

1. Background and purpose of the standard

GB/T 4702.15-2016 is the 15th part of the series of standards for chemical analysis of metallic chromium, which is specifically used to determine the content of lead, tin, bismuth, antimony and arsenic in metallic chromium. With the increasing demand for high-purity metals in industrial development, the importance of accurately detecting impurity elements has become increasingly prominent. This standard adopts advanced inductively coupled plasma mass spectrometry (ICP-MS), which has the characteristics of high sensitivity and low detection limit.

2. Comparison of standard frameworks

Standard number	Applicable elements	Determination method	Release date	Scope of application
GB/T 4702.1	Chromium content	Ammonium ferrous sulfate titration method	2016	Determination of chromium in metallic chromium
GB/T 4702.6	Iron, aluminum, silicon and copper content	Inductively coupled plasma atomic emission spectrometry	2016	Determination of multiple elements in metallic chromium
GB/T 4702.15	Content of lead, tin, bismuth, antimony and arsenic	Inductively coupled plasma mass spectrometry	2016	Determination of trace elements in metallic chromium

3. Implementation Suggestions

Case Analysis: A metallic chromium manufacturer used this standard method and successfully reduced the arsenic content from 0.0015% to 0.0008%, meeting export requirements. The following are key recommendations for implementation:

Instrument calibration:Regularly calibrate the ICP-MS instrument to ensure the accuracy of the mass calibration solution (containing beryllium, cerium, iron, etc.).
Reagent purity:All reagents must be of high purity to avoid the introduction of interfering elements. The resistivity of ultrapure water should be no less than 18MΩ/cm.
Sample preparation:Sampling must be carried out strictly in accordance with GB/T 4010, the sample particle size must pass through a 1.68mm sieve, and be evenly mixed.
Blank test:Perform at least one blank test for each batch of analysis to ensure that there is no pollution to the reagents and the environment.
