摘要：

In this work, syringe membrane micro-solid phase extraction (SMMSPE) was described for the enrichment and separation of Te(IV) and Te(VI) prior to graphite furnace atomic absorption spectrometry detection. SMMSPE device is composed of a syringe and a disk filter, which was filled with flexible titanium(IV) [email protected] nanofiber membrane as the sorbent. The adsorption behavior of Te(IV) and Te(VI) on the sorbent was studied in detail. The results showed that Te(IV) was quantitatively adsorbed on the sorbent in the pH range of 3.0-5.0, whil...
