Determination of nickel(II) by CTAB sensitized fluorescence quenching method of the derivatives of calix[4]arene.
The fluorescence quenching effect of Ni(2+) on the derivatives of p-tert- butyl-calix[4]arene with o-phenanthroline(TBCP) was studied in cetyltrimethyl- ammonium bromide (CTAB) medium. Ni(2+) reacted with the TBCP to form inclusion complex. The fluorescence quenching was sensitized in CTAB. The linear range of calibration curve for the determination of Ni(2+) was 0.050 μg/mL ~ 1.00 μg/mL. The detection limit estimated (S/N = 3) was 5.3 ng/mL. It has been applied for the determination of Ni(II) in samples with satisfactory results.
