Introduction

GB/T 4698.1—2017: Interpretation of the standard for determination of copper content in titanium sponge

Standard dimensions

GB/T 4698.1—2017 requirements

Comparative analysis

Scope of application

Determination of copper content in titanium sponge, titanium and titanium alloys, range 0.10%~5.00%

Replaced the old standard GB/T 4698.1—1996, the determination method was changed from spectrophotometry to flame atomic absorption spectrometry

Analysis method

Flame atomic absorption spectrometry (wavelength 324.7

Actual Application Case

A titanium alloy factory adopted this standard method to detect the copper content of its products. The results showed that the deviation was within the allowable range, which verified the reliability of the method.

Sample sampling and dissolution: weigh 0.10g of sample and add hydrochloric acid and hydrofluoric acid to dissolve it
Test solution preparation: oxidize through nitric acid and mask fluoride ions with boric acid
Standard curve drawing: use copper standard solution to measure absorbance at 324.7 nm and establish working curve
Sample testing and result calculation: calculate the mass fraction of copper according to the working curve and formula

Implementation suggestions

Precautions for the use of this standard in the laboratory:

Ensure that the instrument calibration meets the requirements and the characteristic concentration does not exceed 0.08 μg/mL
Operators need to receive professional training and strictly follow the experimental steps
Blank test and repeatability test must be performed to ensure data reliability
