  Article:   THE SEPARATION OF SOME PRESERVATIVES BY THIN LAYER CHROMATOGRAPHY.

Authors:  CASONI DORINA, BRICIU RODICA DOMNICA, VERES DANIELA.
 
       
         
  Abstract:  

Rapid separation of 18 synthetic preservatives on the silica gel chemically modified HPTLC plates (RP-18F254s, RP-18wF254s, CN F254s and Nano-SIL Diol/UV254) has been achieved with methanol-water as mobile phase. The development distance was 8 cm in all cases. Identification of the separated preservatives was performed by UV light at l=254 nm. Potassium sorbate, sodium benzoate and ascorbic acid were identified in some soft drinks after sample preparation by solid phase extraction on C18 column.
