Carbon Dioxide Sequestration Using Brucite

The magnesium sulfate portion of the buffer is capable of reacting with alkaline solutions, which have a pH above the precipitation point of that of the magnesium ion, for example, sodium hydroxide, lime slurry, and ammonia solution  

This buffering effect produces a neutralized spill with a resultant pH from about 9 to 10, which is significantly less hazardous than the unneutralized spill. The incorporation of pH indicator dyes into the product produces a visual key as to whether the spill is neutralized or requires the addition of 

The antibacterial properties of MgO powder has been studied by Sawai et al. (2000) and has been found to have antibacterial activity toward Escherichia coli and Staphylococcus aureus. It was found that contact between the bacterial cells and the MgO powder was necessary for the bactericidal activity. It is speculated that the generation of active oxygen species, such as O, which was found to be produced by MgO powder, may be the primary factor in its antibacterial activity rather than any effect due to increasing the growth medium pH caused by the MgO. 

Fossil fuels are the major worldwide energy source and will continue to be so for the foreseeable future. This has raised environmental and climatic concerns over increasing levels of anthropogenic C02 emissions. Brucite has
