Introduction

GB/T 6730.52-2018 Standard Interpretation

Chapter Content	Key Information
Scope	Applicable to the determination of cobalt content in iron ore, iron concentrate, sintered ore and pelletized ore, with a mass fraction range of 0.0007% to 0.06%.
Principle of the Method	The sample is decomposed with hydrochloric acid, nitric acid, etc., and after filtration, the absorbance of cobalt is determined by flame atomic absorption spectrometry at a wavelength of 240.7 nm or 252.2 nm.

Standard Background and Technical Evolution Analysis

This standard replaces GB/T 6730.52-2004. The main changes include:

The measurement range is adjusted to 0.0007% to 0.06%
The use of certified reference materials is introduced
The precision expression method is optimized

Instrument and Reagent Requirements

Key Equipment:

Atomic Absorption Spectrometer (with Air-acetylene Burner and Cobalt Hollow Cathode Lamp)
Polytetrafluoroethylene Beaker
Analytical balance (sensitivity 0.0001 g)

Implementation suggestions

To ensure the accuracy of the measurement:

Strictly control the purity of reagents, especially the use of hydrofluoric acid
Regularly calibrate the atomic absorption spectrometer
Blank tests and verification tests are essential
