Fluorinated Compounds In Carpets

Validating methods under epa s sw 846 to measure certain pfas in groundwater surface water wastewater and solids e g soils sediments and sewage.

Fluorinated compounds in carpets. The extremely strong carbon fluorine bond the strongest in organic chemistry makes them thermally. Cleaning compositions and methods for cleaning carpets and other materials are disclosed. This paper reports on a study in a 0 73 kw pilot scale rotary kiln incinerator simulator to qualitatively and where applicable. Once final it will be included in the sw846 compendium.

Phased out due to the increasing evidence that bioaccumulation of the chemicals is significant and that in humans the compounds persist with a. Some of the stain resistant coatings that carpeting is treated with contain perfluorinated compounds pfcs such as perfluorooctanoic acid pfoa and their corresponding homologues c6 c14 acids as well as fluorotelomer alcohols and. The cleaning compositions contain nanolatexes and the methods for cleaning carpets and other materials use such compositions. Epa recently posted a draft method to measure a group of 24 pfas compounds in groundwater surface water and wastewater samples.

Symposium paper one of the emerging waste streams that will likely be disposed of in combustors is carpet due to its high heating value and combustibility. Perfluorinated compounds pfcs are a class of anthropogenic chemicals incorporated over six decades into a wide range of industrial and consumer use products including surface treatments for carpets and textiles paper and packaging non stick cookware firefighting foams and insecticides. The compositions may also contain a source of peroxygen bleach and or a fluorinated compound. Because perfluorinated compounds pfcs repel both water and oil they are used as durable repellent treatments for textiles such as outdoor clothes and for home products such as carpets in addition pfcs are widely used in the production of fluoropolymers such as polytetrafluoroethylene trade name teflon which is widely used in coatings for electronic automotive and outdoor products.
