Water Analysis – Multimedia

Water is ubiquitously used in labs for preparing standards, samples, reagents, media, for cleaning glassware and even as a medium in which reactions are carried out.

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.

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.

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.

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.

In this Teach Me in 10, we hear from field application scientist Marc Elie on the challenges of PFAS analysis in matrices including drinking water and wastewater and how to mitigate interference and contamination on LC-MS/MS instrumentation.
