Inorganic bromine is found in the atmosphere and is quickly cycled between its gas and its particulate phase. Bromine gas (Br 2 ) undergoes an autocatalytic cycle known as the ' bromine explosion ', which occurs in the ocean and salt lakes such as the Dead Sea , where a high quantity of salts are exposed to the atmosphere.
In 1840, bromine was discovered to have some advantages over the previously used iodine vapor to create the light sensitive silver halide layer in daguerreotypy. [ 25 ] By 1864, a 25% solution of liquid bromine in .75 molar aqueous potassium bromide [ 26 ] was widely used [ 27 ] to treat gangrene during the American Civil War, before the ...
During his research on mineral salts he discovered bromine in 1825, as a brown gas evolving after the salt was treated with chlorine. [1] [2] [3] After working at the University of Heidelberg and the University of Zurich he became the successor to Robert Wilhelm Bunsen at the University of Breslau. He worked and lived in Breslau until his death ...
All the world's bromine production is derived from brine. The majority is recovered from Dead Sea brine at plants in Israel and Jordan, where bromine is a byproduct of potash recovery. Plants in the United States (see: Bromine production in the United States), China, Turkmenistan, and Ukraine, recover bromine from subsurface brines. In India ...
The high-bromine brines in the Appalachian Basin are found in Silurian and Devonian rocks, in Pennsylvania, Ohio, and West Virginia. The principal source of the brine in Ohio and West Virginia was the Pottsville Formation, also called the Big Salt Sand. In Pennsylvania, bromine brine was pumped from the Pocono Sandstone. [2]
Oceanographers explored an area around the Pacific Ocean’s Nazca Ridge and found a massive underwater mountain. Using a sonar system, the researchers digitally mapped the seafloor of the area ...
NOAA researchers with the Okeanos Explorer expedition recently captured a video of a glowing shrimp with some crazy antennae.
Using acoustic measurement instruments to record the ocean's sounds during the daily periods of up and down travel, the team found a three to six decibel increase in noise compared to the norm.
