Determination of Silicon in Water: Presence of Silicon in Water

What is Silicon? What are the Areas of Use?

Silicon is a chemical element with the symbol “Si” and atomic number 14 in the periodic table. It is the second most abundant element on Earth after oxygen.

Areas of Use

Electronics and Semiconductor Industry: Silicon is widely used in electronic circuits, transistors, integrated circuits and solar panels due to its semiconductor properties.
Glass and Ceramic Production: Silicon dioxide is one of the key ingredients in making glass and ceramics.
Metallurgy: Silicon is used as an additive in the production of steel and aluminum. Silicon alloys increase the strength and corrosion resistance of metals.
Chemical Industry: Silicon is used in the production of organosilicon compounds called silicones. Silicones are found in a variety of products such as adhesives, sealants, lubricants and medical implants.

Silicon, also known as silicon, makes up 28% of the lithosphere. It is characteristic of all major rocks except carbonates. It is classified as the most abundant element, especially in igneous rocks.

Presence of Silicon in Water

Although it dissolves very little in water, it is known that most of the silicon in water originates from the degradation of silica-containing minerals. The type, composition and pH of silica-containing minerals are factors that affect the solubility and form of silica in the solution obtained after contact with water. Silica can exist in water in three different states:

Suspended
As colloid
In solution

Natural Resources and Availability

Natural Sources: In rivers, lakes, seas and groundwater, silicon usually occurs by dissolution of silicate minerals.
Dissolved Form: Silicon is usually soluble in water as monosilicic acid (H₄SiO₄). This form may vary depending on the conditions of the water, such as pH and temperature.

Behavior of Silicon in Water

pH Level: Depending on the pH level of the water, silicon can exist in different forms. At neutral and slightly alkaline pHs it may be in the form of dissolved monosilicic acid, and at higher pHs it may be in polymeric silicate forms.
Solubility: The solubility of silicon depends on factors such as the temperature and chemical composition of water. Solubility generally increases with increasing temperature.
Colloidal Form: In some cases, silicon can be found in water as colloidal particles (small, dispersed particles).

The expected amount of silica in natural waters is in the range of 5-25 mg/L. In some measurements, it has been observed up to 100 mg/L depending on the region.
