N1,N2-Bis [1-(2-hydroxyphenyl)methylidene]ethanedihydrazide as a neutral ionophore for preparation of a new Ho3+ PVC-membrane sensor
摘要:
N1,N2-Bis [1-(2-hydroxyphenyl)methylidene]ethanedihydrazide(MEH)was used as new compound which plays the role of an excellent ion carrier in the fabrication of a Ho(Ⅲ)membrane electrode.The electrode shows a good selectivity for Ho(Ⅲ)ion with respect to most common cations including alkali, alkaline earth, transition and heavy metal ions.This electrode has a wide linear dynamic range from 1.0×10-6 to 1.0×10-2 mol/L with a Nernstian slope of 19.8±0.3 mV per decade and a low detection limit of 5.8×10-7 mol/L in the pH range of 2.5-9.8, while the response time was rapid( < 10 s).The suggested sensor was applied to the determination of Ho(Ⅲ)ions in tap water and river water samples.
