Preparation of Bromine from Bittern

MAP precipitation from landfill leachate and seawater bittern waste.

The leachates generated at Hong Kong landfill sites contain high strength of ammonium-nitrogen (NH4+-N) over 3,000 mg l(-1) and are generally inhibitive to most biological treatment processes. To remove the NH4+-N from the landfill leachates and also recover the nitrogen as a struvite fertilizer, a lab-scale study was performed to investigate the feasibility of NH4+-N removal and struvite cryst...

The history of bromine from discovery to commodity

The discovery of bromine represents one of the first experimental evidences that elements could be grouped in families of similar properties. Transformation of the new element and its derivatives into a commercial reality had to wait until automobiles begun to be mass-produced. The pattern end use of bromine has reflected the changes in social appreciation of environmental protection and safety...

Development of a Bromine Oxide Product from Gome

Bromine monoxide (BrO) is an atmospheric constituent playing an important role in the chemistry of both the stratosphere and the troposphere. Recent studies have demonstrated that BrO total columns can be retrieved on a global scale by analysis of backscattered solar spectra measured by the Global Ozone Monitoring Experiment (GOME), aboard the ERS-2 satellite since April 1995. The data analysis...

Preparation of Sulfur Mortar from Modified Sulfur

Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...
