Heavy metal capture agents (heavy metal capture agents) can be used in the field of sewage treatment. my country’s research and development enthusiasm is high

Heavy metal trapping agent, also known as heavy metal trapping agent and heavy metal precipitating agent, is a chemical agent that strongly chelates heavy metal ions. Heavy metal capture agents have the advantages of safety, non-toxicity, good flocculation effect, and low dosage. They are widely used in the field of sewage treatment. Printing and dyeing plants, mining areas, electronics factories, waste incineration plants, metallurgical plants, etc. are their main application scenarios.

​​According to different substrates, heavy metal capture agents can be divided into three types: sulfhydryl heavy metal capture agents, xanthate heavy metal capture agents and dithiocarbamate (DTC) derivatives. Thiol-based heavy metal capture agents are usually made from a combination of polymer materials and mercapto-based compounds, and have excellent treatment effects on gold, mercury and other metals; xanthate-based heavy metal capture agents have poor chemical stability and high production costs, and are not suitable for Suitable for large-scale use; DTC derivatives are the most widely used heavy metal capture agents and can capture various heavy metal ions.

According to the “2023-2028 China Heavy Metal Collecting Agent (Heavy Metal Collecting Agent) Industry Market In-depth Research and Development Prospects Forecast Report》 shows that heavy metal capture agents are mainly used in the field of wastewater treatment, including electroplating wastewater treatment, metallurgical wastewater treatment, chemical wastewater treatment, urban domestic wastewater treatment, mine tailings wastewater treatment, etc. Benefiting from the deepening of environmental protection concepts, the prosperity of my country’s sewage treatment industry continues to increase. According to data released by the Ministry of Housing and Urban-Rural Development, there will be 2,827 urban sewage treatment plants in my country in 2021, with a sewage treatment rate as high as 98%. As the development of downstream industries accelerates, the market demand for heavy metal capture agents in my country is becoming increasingly strong.

In recent years, attracted by market prospects, my country’s enthusiasm for the research and development of biomass heavy metal capture agents has continued to rise. In June 2023, a research team of college students from Guangdong Shunde Vocational and Technical College successfully prepared a high-efficiency biomass heavy metal capture agent using biomass raw materials. This product has the advantages of green environmental protection, low production cost, wide application range, and efficient capture. It is expected to be widely used in the field of sewage treatment in the future.

The main manufacturers of heavy metal capture agents in my country include Henan Kaijie Water Treatment Co., Ltd., Shenzhen Changlong Technology Co., Ltd., Sainz Environmental Protection Co., Ltd., Shenzhen Lvcheng Environmental Protection Technology Co., Ltd., Suzhou Qingkong Environmental Protection Technology Co., Ltd., etc. There are many heavy metal capture agent manufacturers in my country, but the market lacks leading companies with high-performance product production capabilities, and its industry concentration needs to be improved.

Industry analysts said that with the accelerated development of the sewage treatment industry, the market demand for heavy metal capture agents as water treatment agents will continue to grow. . In recent years, driven by environmental protection policies, my country’s heavy metal capture agent industry has gradually developed in a green and environmentally friendly direction, and biomass heavy metal capture agents are expected to become the mainstream of the market in the future. In terms of market competition, with the improvement of independent research and development capabilities of local enterprises in the future, the concentration of my country’s heavy metal capture agent industry is expected to increase.
