Introduction

GB/T 23950-2024 Standard Overview

This standard specifies the general method for the determination of heavy metals in inorganic chemical products, including limit colorimetry and inductively coupled plasma optical emission spectrometry (ICP-OES). It is applicable to the detection of various heavy metal elements such as iron, lead, copper, etc. in inorganic chemical products.

Main new contents

New contents	Detailed description
Sample processing chapter	A detailed sample processing process has been added to ensure the accuracy of the test results.
Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES)	New methods for the detection of various heavy metal elements, including copper, zinc, cobalt, etc.

Implementation Recommendations

ICP-OES is recommended:

Applicable to the detection of various heavy metal elements, including copper, zinc, cobalt, nickel, etc.
Pay attention to instrument calibration and matrix matching issues. It is recommended to use internal standard method or background subtraction method to eliminate interference.
When processing data, ensure the accuracy of the standard curve and record all operation steps to ensure traceability.
