Introduction

Analysis of the core content of the standard

Technical indicators	Requirements of HJ 1007-2018	Comparison of similar methods
Method detection limit	0.2 mg/m³	40% lower than the traditional chemical method
Applicable industries	Mainly steel industry	Extended to chemical and metallurgical fields
Sampling volume	200L standard dry volume	Consistent with HJ/T 397

Key Technical Points

Note that when using inductively coupled plasma optical emission spectrometer for measurement:

Plasma flow rate is controlled at 1.5L/min±5%
The characteristic spectrum line of sodium element is selected at 589.592nm
The correlation coefficient of the standard curve must be＞0.999

Implementation Application Case

The exhaust gas monitoring of the sintering machine head of a steel plant showed that the alkali mist concentration measured by the heating leaching method was 3.45±0.28mg/m³, and the spike recovery rate reached 102%, which was in line with the standard requirement of 95%-105%.

Quality control requirements

Two blank controls are required for each batch of samples
The sampling tracking rate is controlled at 1.0±0.1
The error of the intermediate concentration calibration point is ≤±10%

Background of standard evolution

This standard introduces ICP-OES technology into the monitoring of alkaline mist from fixed pollution sources for the first time. Compared with the traditional acid-base titration method:
