Optimized Conditions

In this study, a simple and effective method for the determination of organic phosphorus in environmental water samples using ionic liquid (1-butyl-3-methyl-imidazolium hexafluorophosphate, BmimPF6) head space fiber liquid-phase microextraction combined with high-performance liquid chromatography (HPLC) has been developed. The effects on the extracting efficiency such as the pH of the sample solution, the concentration of NaCl, etc., were investigated. Under optimized conditions, the value of the extracting efficiency can reach 289 for parathion.
