sulfonate

To speed this transport even more, Yang and his team also modified their triazine starting materials so that the rigid pores were lined with negatively charged sulfonate groups.

Compounds used in flame retardants and batteries, for example, contain a sulfonate group instead of a carboxylic acid group and won’t break down with this approach.

The advisory was issued Friday after elevated levels of perfluorooctane sulfonate were found in surface water from ponds near the Boulder Creek development in Belmont, northeast of Grand Rapids.

The Rutland Herald reports elevated levels of perfluoroalkyl sulfonate, or PFAS, were found in two wells that serve the Rutland Airport Business Park.

The suit, which seeks class action status, alleges the defendants should have known perfluorooctane sulfonate and other chemicals would pose health and environmental risks.
