Hollow Fiber Liquid Based Microextraction of Nalidixic Acid in Urine Samples Using Aliquat 336 as a Carrier Combined with High-Performance Liquid Chromatography.


A new and simple hollow fiber liquid-phase microextraction was used in conjunction with HPLC for the extraction and quantitative determination of nalidixic acid (NA) in human urine samples. This study considers this technique an alternative to common methods of hollow fiber microextraction based on pH gradient and electromembrane extraction of NA in human… (More)
