Lightweight magnesium oxide as a new type of inorganic salt magnesium new materials, magnesium oxide has a large Magnesium Sulphate producer specific surface area, strong adsorption, high activity reaction advantages, in recent years in the field of environmental protection, market research and development and application research more and more, magnesium oxide can deal with environmental water treatment, sulfur dioxide, industrial organic waste gas, dyes, pesticides, heavy metal ions and other related uses. Lightweight magnesium oxide materials due to their large specific surface area, larger than ordinary magnesium oxide products, and the product adsorption is strong, high reactivity characteristics, in the water, soil, and other environmental protection treatment field application prospects. The market price of lightweight magnesium oxide is high, and the large-scale application of large-scale application in many fields is more limited. Why is magnesium oxide called a new material? 
Magnesium oxide and magnesium hydroxide belong to the same inorganic materials, which itself has non-toxic characteristics, water treatment agent mainly refers to the removal of harmful substances in the water chemical additives general term, at present most of the water treatment agents Magnesium Oxide MgO have speciality, need to combine water quality to better treatment, to achieve the demand for treatment. Reasonable selection of water treatment agents can better play its value.
Magnesium oxide and magnesium hydroxide because of the characteristics of good activity, especially magnesium oxide has the characteristics of high activity, large specific surface area, can quickly adsorb various impurities in water, magnesium hydroxide and magnesium oxide are alkaline substances, in addition to adsorption can also neutralize the pH of water. Magnesium oxide can treat wastewater containing chromic acid, in the wastewater containing chromic acid to add magnesium oxide can adsorb chromium ions in a short time, and this process is not affected by temperature, the treatment efficiency is stable, through repeated tests Magnesium Oxide powder can be concluded, the treatment of chromium can also be at the same time in the wastewater in all kinds of harmful substances and solid suspended substances to get effective removal, proving that magnesium oxide and magnesium hydroxide have a high application value and market prospects.
