Flow Techniques

An automated method is described, using standard continuous flow techniques, for the determination of urine fluoride ion concentration using a fluoride ion selective electrode. It is shown that the kinetics of the electrode response to changes in fluoride ion can be used for the accurate measurement of fluoride ion concentration in urine, and that equilibration of the electrode response is not a prerequisite for the measurement of fluoride ion. Recovery experiments are in the range 83 to 90%; in-batch precision is between 0·9 and 1·6% and carryover 2·5% or less.

Cadmium(II)-imprinted polymer [Cd(II)-IIP] was synthesized without using the conventional complexing ligand to reduce unnecessary step for complexing Cd(II). During synthesis of Cd(II)-IIP, the complete removal of Cd(II) from the polymer was confirmed using EDAX and AAS. Synthesized polymers ([Cd(II)-IIP], non-imprinted polymer (NIP) and polymer with cadmium (CdP) were also characterized and compared. SEM analysis of Cd(II)-IIP indicated the changes in surface morphology after imprinting, the polymer looked like a flaky material in comparison with NIP and CdP. BET surface area of Cd(II)-IIP (68 m2/g) was found to be more than that of NIP (24.6 m2/g) and CdP (17 m2/g). Cd(II)-IIP formed a complex with Cd(II) in the solution through carbonyl oxygen of the acrylamide as confirmed by FTIR. TGA analysis showed less char yield for Cd(II)-IIP than NIP. Cd(II)-IIP was further explored for the fabrication of ion selective electrode (ISE), which on binding with Cd(II) gave higher potential than NIP-ISE. Interference study was also performed using Cd(II)-IIP as such and also with fabricated ISE with Cd(II)-IIP using different cations such as Pb(II), Zn(II), Mn(II), Hg(II), and found that imprinted polymer showed more selectivity towards Cd(II) in aqueous solutions.
