Introduction

GB/T 4698.28—2017 Standard Interpretation

This standard specifies in detail the determination method of ruthenium in sponge titanium, titanium and titanium alloys, using inductively coupled plasma atomic emission spectrometry (ICP-AES), which is suitable for the detection range of ruthenium content of $0.05\% \sim 0.50\%$.

Background of Standard Formulation

With the wide application of titanium and titanium alloys in aerospace, petrochemical and other fields, accurate determination of their impurity element content has become a key link in product quality control. As an important specification in the field of titanium material testing in my country, the GB/T 4698 series of standards provide technical support for ensuring product performance and safety.

Technology Evolution Analysis

Determination Method	Scope of Application	Comparison of Advantages and Disadvantages
Flame Atomic Absorption Spectrometry	Applicable to trace element analysis	High sensitivity and easy operation; but sensitive to matrix interference
Inductively Coupled Plasma Atomic Emission Spectrometry	Applicable to simultaneous determination of multiple elements	High sensitivity, low detection limit, suitable for analysis of complex samples
Spectrophotometry	Suitable for quantitative analysis of specific metal ions	Easy to operate but with low sensitivity

Actual application case

Background:An aerospace company needs to test the ruthenium content in a batch of titanium alloy parts to ensure that they meet international standards.

Steps:

Sampling in accordance with GB/T 4698.28-2017
Sample digestion and determination using Inductively coupled plasma atomic emission spectrometer
The mass fraction of ruthenium is calculated using the working curve

Results:The test results show that the ruthenium content in this batch of titanium alloy is $0.12\%$, which meets the quality requirements.

Implementation recommendations

The laboratory should be equipped with a high-precision inductively coupled plasma atomic emission spectrometer
Operators should receive professional training to ensure the accuracy of the experimental process
It is recommended to calibrate the instrument regularly and update the standard solution to ensure long-term detection stability
