Silicon dioxide - Wikipedia
Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of sand.Silica is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.read more
REPORT ON SILICA REMOVAL BY PRECIPITATION
(i) Add about 1 mil of water and 6 drops of sulphuric acid (1:1) to the Silica precipitate. Add 15mL HF and evaporate to dryness and then heat at a gradually increasing rate until sulphuric acid is removed. Ignite for 10 min at 1100 – 1150 0C, cool in desiccator, and weight. The difference is weight of silica…read more
The functions of lime in water treatment
Calcined dolomite (CaO MgO), can also be used in water treatment plants, for example to eliminate silica from water. This is because the magnesium in the dolomite acts as the main reactive agent for the elimination of silica. The use of quicklime and slaked lime is much less common.read more
