Measurement of Water Pollutants

Photocatalytic Degradation of Organic Pollutants in Water

A photocatalyst is defined as a substance which is activated by adsorbing a photon and is capable of accelerating a reaction without being consumed [1]. These substances are invaria‐ bly semiconductors. Semiconducting oxide photocatalysts have been increasingly focused in recent years due to their potential applications in solar energy conversion and environmen‐ tal purification. Semiconductor ...

Emerging Measurement Techniques for Airborne Pollutants

The quality of the air we breathe in many parts of the world has been improved dramatically by a series of clean air regulations dating back over fifty years, including the “clean air acts” passed by the UK government (1956) [1], the federal governments of USA (1963), and those passed by many other countries. As a result, the health of the human population and our surrounding aquatic and terres...

Measurement of Fluoride Concentration in Semnan Drinking Water Distribution

Background: The existence of fluoride ion in potable water has distinctive effects on human health. Fluoride is attracted by positively charged calcium in teeth and bones due to its strong electro-negativity which results in dental, skeletal, and non-skeletal forms of xuorosis and associated health complaints in children as well as adults. Methods: Water samples from groundwater used for dri...
