Determining the removal effectiveness of flame retardants from drinking water treatment processes
… organophosphoric acid triester flame retardants tributyl phosphate, tri(2-chloroethyl) phosphate, and ethanol, 2-butoxy-, phosphate (3:1) were measured after major treatment processes at the Chattahoochee Drinking Water Plant in Atlanta, Georgia, USA. The findings indicated significant removal of …

Natural attenuation of organophosphates in river systems: Chattahoochee River case study
Three organophosphoric acid triesters, tributyl phosphate (TBP), tris(2-chloroethyl) phosphate (TCEP), and tris(2-butoxyethyl) phosphate (TBEP) have been detected in surface waters across the world, primarily the result of sewage treatment plant discharge. Despite concentrations as low as a few …

Understanding aggregation of solvating extractants in applied separations
… relevant to applied separations. The extractant tributyl phosphate (TBP) is used in the Plutonium Uranium Reduction Extraction (PUREX) process for recovering uranium and plutonium from used nuclear fuel. The extractant N,N,N',N'-tetraoctyl diglycolamide (TODGA) is being considered for use in the …

Interactions of Environmental Pollutants with Human Gut Bacteria
… bioaccumulated, while boscalid, propiconazole, tributyl phosphate and triphenyl phosphate showed both interaction types depending on the bacterial strain. PFOA and PFNA belong to the chemical group of per-/poly-fluoroalkyl substances (PFAS) – the so called “forever chemicals”. PFAS are a major …
