Ionic-liquid-based aqueous biphasic systems for improved detection of bisphenol A in human fluids

resumo

Bisphenol A is a human endocrine disruptor. Its normally low levels in biological fluids make it difficult to detect via conventional techniques. This work demonstrates the complete extraction of bisphenol A, and its possible concentration up to 100-fold in a single-step procedure, using ionic-liquid-based aqueous biphasic systems.
