Determination of Silica

Silicon, which makes up 28% of the lithosphere, is the most abundant element like oxygen. Silica is slightly soluble in water and is found in natural waters through the gradual decomposition of silica-containing minerals. Silica can be found as suspended particles, colloids and solutions in water. Depending on the pH state, it can exist as silicic acid or silicate ion. Generally, silica is found in the range of 5 to 25 mg/L in natural waters, but depending on conditions, it can be over 100 mg/L in some areas.

The amount of silica in water is especially important in industrial activities such as steam production and cooling water systems. Under certain conditions, especially in high-pressure steam systems, problematic silica and silicate deposits can form.

Badness that may occur in production processes can be prevented by determining silica in natural and waste water. Information can be obtained about the water sample taken.
