| Abstract: | A spectrophotometric method for the quantitative determination of polyethylene glycol 600(PEG 600) in urine is based on partitioning a chromophore present in ammonium ferrothiocyanate reagent into an aqueous phase and a chloroform phase in the presence of PEG.The method is simple and reproducible,and can detect PEG in a concentration of 0 25 g/L.It gives a linear response over a range of 0 25 2 5 g/L.The recovery of PEG 600 in urine is 107% and reletive standard deviation is less than 5%. |
