TKN Analysis of Environmental Samples: Soil and Wastewater Kjeldahl Nitrogen Determination

In this video, we take a show TKN analysis, a critical method for determining total Kjeldahl nitrogen (TKN) in soil and wastewater samples.

TKN is a key indicator of the nitrogen content in environmental samples, providing critical information for monitoring and assessing environmental impacts. We demonstrate each step of the Kjeldahl method for TKN determination, which involves digestion, distillation and titration, and how it can be applied to both soil and wastewater samples.

Burning Forever Chemicals With Water

Forever chemicals are extremely useful in industry, but they can also leak into the environment, your drinking water and your blood. And they last (practically) forever. But now chemists have a new way to destroy them: burning them with water.

Using Magnetic Rust Nanoparticles To Clean Water

Researchers have developed modified iron oxide particles, known as "smart rust", that can grab onto pollutants in water and help with their cleanup. The new method is cheaper and more simple than other alternatives, they say.

The Evolution of Wastewater-Based Epidemiology

For over 150 years, wastewater has provided a rich source of data for tracking infectious diseases and informing public health decisions. Since the COVID-19 pandemic, the scope for wastewater-based epidemiology (WBE) has increased significantly and requires increasingly rapid, versatile and accurate detection methods to monitor the spread of disease.

Enhanced PFAS Detection for Safer Drinking Water

Per-and polyfluoroalkyl substances (PFAS) are pervasive in our environment. Although they are found in a wide variety of household objects, they are associated with negative health effects. They can also be found in our drinking water.

Volatile Organic Compounds Analysis in Drinking Water

One method of analysis commonly used to ensure drinking water quality is the measurement of volatile organic compounds (VOCs). These compounds can appear in drinking water by contamination from numerous sources, including industrial and commercial operations.
