Research has found that the burning of coal produces tiny particles of potentially harmful titanium oxide. When these nanoparticles are inhaled, they enter the lungs and possibly the bloodstream. Negative ions can effectively remove these nanoparticles and prevent pollutants from causing damage to the human body.
Studies by global research teams show that these particles can travel great distances unless captured using high-tech technology. Dr. Michael Hirschla, Distinguished Professor in Virginia Tech's School of Geosciences, is the leader of the research. The problem, he believes, is that there is no simple, practical way to prevent the formation of titanium nanoparticles when coal is burned.
Coal-fired power plants in the United States use advanced technology, coupled with the supervision of the Clean Air Act and the Environmental Protection Agency. Before the final emission of the exhaust gas from the power plant, the nanoparticles and some tiny particles will be eliminated. Remove. However, for underdeveloped countries where particulate matter produced when coal is burned cannot be effectively removed, low-priced titanium oxide nanoparticles and many other types of particulate matter are emitted into the atmosphere, causing haze in some countries to some extent.
Dr. Herschla, together with Richard Jan Giulio, a professor of environmental toxicology at Duke University, and doctoral candidate Jessica Brandt, conducted a preliminary biological toxicity test on the particles. Tests have shown that the particles are potentially toxic.
Negative ions are a green and environmentally friendly treatment method that can effectively remove these harmful particles. Ultra-fine purification is the unique performance of ecological-grade negative ions, designed to purify ultra-fine particles. According to research by many experts in the field of air environmental protection in the United Nations, ecological-grade small-particle negative ions can actively capture small particles of dust and cause them to condense and settle, thereby effectively removing dust particles of 2.5 microns (PM2.5) and below in the air, and even For particles below 1 micron, the smaller the particles, the better the purification effect. Therefore, the harm of fine particles to human health can be reduced. There are a dazzling array of negative ion machines on the market, but due to the different levels of negative ion generation technology, large, medium and small particle size negative ions will be generated. Tao Mingzhang, a researcher at the China Air Negative Ion and Ozone Research Society, said that only negative ion generators that use ecological negative ion generation chip technology (Patent No.: 201220433901.6) and nanofullerene negative ion release technology (Patent No.: ZL201020263299.7) can generate Equivalent to nature, easy to enter the human body, highly active, ecological grade small particle size negative ions.
The ultra-fine purification of negative ions has been recognized by authoritative institutions and the public. The market share of negative ion generators has increased year by year, which is the most favorable proof. Faced with the dangers of fine particles and the urgent need for high-quality air, negative ion generators that can achieve ultra-fine purification will become the most effective tool.
