On-cartridge derivatisation using a calixarene solid-phase extraction sorbent for facile, sensitive and fast determination of formaldehyde in beer
Z Deng, K Hu, Y Zhang, W Zhao, F Wang, L Guo… - Food chemistry, 2016 - Elsevier
This work demonstrates the successful application of an on-cartridge derivatisation
procedure for facile, fast and sensitive determination of formaldehyde in beer by HPLC-UV.
The derivatisation and solid-phase extraction (SPE) were integrated into a novel calixarene
SPE sorbent: tetraazacalix [2] arene [2] triazine bonded silica gel. Specifically, 2, 4-
dinitrophenylhydrazine was adsorbed onto the sorbent in advance, based on the charge-
transfer interaction between the macrocyclic molecule and nitrobenzenes. The method was …
