Ag. Dedov et al., Use of solid-phase extraction for sample preparation in determination of phenols in aqueous solutions, PETR CHEM, 40(1), 2000, pp. 55-59
The solid phase extraction of phenols with Diapak C16 concentration cartrid
ges as a sample preparation method for spectrophotometric, fluorescence mea
surement, or electrochemical detection was studied. The use of the solid-ph
ase extraction technique was shown to give satisfactory results with these
analytical detection methods for both model and real samples.
