Introduction

1. Standard Overview

GB/T 6730.36-2016 specifies the method for determining the copper content in iron ore using flame atomic absorption spectrometry, which is applicable to the analysis of natural iron ore, iron concentrate and agglomerates, with a determination range of 0.004% to 0.8% by mass.

2. Background of Standard Revision

This standard replaces GB/T 6730.36-1986. The main revisions include adding warnings, normative references, adjusting sample decomposition steps and calculation formulas, and introducing oxide conversion factors. Compared with the international standard ISO 5418-2:2006, the main difference lies in the optimization of reagent dosage and method details.

3. Comparison of standard frameworks

Standard items	GB/T 6730.36-2016	ISO 5418-2:2006
Scope of application	Iron ore, iron concentrate and agglomerate, etc.	Applicable to iron ore and its products
Measurement wavelength	324.7 nm	324.7 nm
Reagent requirements	Analytical pure reagents, secondary water	Purity requirements are consistent

4. Explanation of professional terms and application cases

Case study: Application of oxide conversion factor

When the copper in the sample exists in an oxidized state, the oxide conversion factor is required to convert CuO to the content of metallic copper. For example, if w(CuO) = 0.1% in the sample is measured, the formula is used to calculate w(Cu) = 0.0809% (calculation: w(Cu) = 0.1% × (1 - 0.2518)).

5. Implementation suggestions

Ensure that the instrument calibration meets the sensitivity and linearity requirements, and perform regular maintenance to maintain stability.
Operators need to receive professional training and be familiar with safety procedures and equipment operating specifications.
The laboratory should be equipped with appropriate ventilation facilities, especially when handling strong acidic reagents.
It is recommended to use a high-sensitivity instrument with a background corrector to improve the accuracy of low-concentration detection.
