The great scientific discovery of 1889: How did German scientists reveal the mystery of negative oxygen ions for the first time?
In 1889, German scientists discovered the existence of negative oxygen ions for the first time. This discovery initiated in-depth research on negative oxygen ions and brought about earth-shaking changes in the scientific community's understanding of charge balance in the air. Negative oxygen ions are mainly composed of negatively charged oxygen molecules or ion clusters, which play an important role in human health and the maintenance of the earth's ecosystem.
Study history
"The discovery of German scientists Elster and Gettel marked the beginning of negative oxygen ion research."
As time went by, German physicist Philippe Edward Anton Leonard first explained the impact of negative oxygen ions on the human body at the end of the 19th century. Subsequently, scholars further explored its biological significance. In 1932, the world's first medical negative oxygen ion generator was launched in the United States, ushering in the application of negative oxygen ions in medical treatment. With the advancement of science, Professor Kruger of the University of California, Berkeley, conducted pioneering research on this topic in the mid-20th century. His experiments proved that negative oxygen ions can affect the biological endocrine and internal circulation of animals and plants. .
Generation mechanism
The generation of negative oxygen ions mainly relies on two methods, natural and artificial. In the air, due to the presence of moisture, negative oxygen ions often combine with water molecules to form hydrates, which prolongs their survival time. Through the reactions of various gas molecules, many negative oxygen ions such as O-(H2O)n, O2< /code >-(H2O)n etc. are widely found in nature.
Generation method
Natural generation of negative oxygen ions includes waterfall effect and tip discharge of plants, while artificial methods mostly use corona discharge and water vapor generation technology. The two products differ in quantity and environmental health effects. In particular, although artificial methods can produce a large amount of negative oxygen ions, the type and concentration are not comparable to those produced in nature.
Natural environment and artificial ionization
"Waterfalls, lightning and plants are natural sources of negative oxygen ions."
In water-rich environments such as waterfalls or seaside, the production of negative oxygen ions makes people feel relaxed because these environments are filled with fresh negative oxygen ions. Lightning generates a large amount of negative oxygen ions, during which the air is bombarded by charged particles and ionized. The corona discharge method of artificially generating negative oxygen ions releases high-speed electrons through high-voltage electrodes, thereby repeatedly generating negative oxygen ions.
Detection methods and applications
"Negative oxygen ions have significant effects in health promotion and environmental improvement."
The measurement of negative oxygen ions mainly uses changes in gas conductivity to determine their presence, and their identification usually relies on mass spectrometry technology. These negative oxygen ions are very beneficial to promoting cardiovascular health and mental health of humans and animals. In addition, their application in improving indoor air quality is gradually becoming recognized. As scientific research shows, negative oxygen ions can effectively remove harmful substances in the air and improve the quality of the living environment.
End
Through the above discussion, we can see the importance of negative oxygen ions in scientific research and daily life. In the future, will there be more unexpected breakthroughs and applications in this field?
