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.

New Model Provides Never-Before-Seen Views of Atmospheric Aerosols

New computer simulations to represent the real conditions of newly formed sea spray aerosols have been designed. The researchers hope this “computational microscopy” will help improve understanding of and predict climate impacts of sea spray aerosol.
