Which of the following materials is suitable for Water Purification?

The correct answer is Zeolites

Key Points

Zeolites: 

• Zeolites are suitable for water purification.
• Zeolites are natural or synthetic minerals that have a porous structure, and their unique structure makes them an excellent material for water purification.
• They can be used to remove impurities such as heavy metals, ammonia, and radioactive materials from water.
• Asbestos, silicone, and quartz are not commonly used for water purification, as they do not possess the necessary properties for effective water treatment.
• Asbestos is a hazardous material and is not recommended for any purpose due to its carcinogenic properties.
• Silicone and quartz do not have the necessary porous structure to effectively remove impurities from water.

Additional Information

The hardness of water:

• Hardness in water is that characteristic that prevents the formation of sufficient leather or foam when such hard water is mixed with soap.
• It is usually caused by the presence of calcium and magnesium salts present in water, which form scum by reaction with soap.

• It may be Temporary hardness or Permanent hardness.
