.
The Yangtze River Delta region is one of the regions with the most active economic development, the highest degree of
openness and the strongest innovation ability in China.
Promoting the integrated development of the Yangtze River Delta, enhancing the innovation and competitiveness of the Yangtze River Delta region, and improving the degree of economic agglomeration, regional connectivity and policy coordination efficiency are of great
significance to leading the high-quality development of the country and building a modern economic system.
In 2019, the Outline of the Yangtze River Delta Regional Integration Development Plan was issued, and the regional integration development of the Yangtze River Delta has become China's national strategy

.
Strengthening the joint management of ecological environment is an important part of the integrated development of
the Yangtze River Delta.
Environmental monitoring standards are the basis of ecological environmental protection, so the Yangtze River Delta region has also begun to formulate corresponding local standards
.
In April 2021, the Market Supervision Administration of Shanghai, Jiangsu Province and Zhejiang Province jointly approved the issuance of the technical specifications for three integrated demonstration zones, including the Technical Specifications for the Monitoring of Volatile Organic Compounds in the Yangtze River Delta Ecological and Green Integrated Development Demonstration Zone, which are the first batch of unified standards
in the field of environmental protection in the Yangtze River Delta Integrated Demonstration Zone.
Since then, the unified local standards in the Yangtze River Delta region in the field of environment have gradually increased, providing important assistance
for the joint management of the ecological environment in the Yangtze River Delta region.

"Determination of Chlorine Gas from Fixed Pollution Source Ion Chromatography Method" specifies the ion chromatography method for the determination of chlorine gas in the waste gas of fixed pollution source, which is suitable for the determination
of chlorine gas in the waste gas of fixed pollution source.
The method principle is that the exhaust gas sample passes through a heated sampling tube
.
Particulate matter
is filtered through a membrane at the end of the sampling tube.
Chlorine gas is absorbed by sodium hydroxide solution to form chloride ions and hypowinate
.
Sodium thiosulfate then reacts with hypocarbonate to form chloride ions
.
The specimen is separated
by an ion chromatography column.
Conductivity detector detection, qualitative according to the retention time of chloride ions, peak area or peak height quantification
.

The formulation of the revised standard has further promoted the progress of unifying the ecological and environmental standards in the Yangtze River Delta Ecological and Green Integrated Development Demonstration Zone, and also provided a new standard for the monitoring of waste gas from fixed pollution sources, which is conducive to the ecological environmental protection
of the Yangtze River Delta region.
