Abstract

This study describes flow-injection spectrophotometric methods for the determination of Ni (ll) Nickel in analytical sample by a new reagent MTDTCH.

An accurate and sensitive flow injection (FI) Spectrophotometric methods have been developed for the determination of ion Nickel (ll) in aqueous solution by preparing the new organic -Schiff base- reagent was prepared by reaction 3-methylthiophene-2-carbaldehyde with hydrazinecarbothiohydrazide. This reagent was worked as a ligand by reacting with the Nickel (II) ion to form a Nickel complex and determination trace amounts of it. The absorbance of the reaction was measured in the injection system which gave the wavelength of 357nm. With a limit of detection of 0.050 µg.mL-1 and a limit of quantitation of 0. 169 µg.mL-1 Relative standard deviation 0.495 and Recovery is 99.50, the metal concentration obeys Beer's law within the range0.5-9.mL-1 with a correlation coefficient value of 0.9997 . The complex composition was specific to the UV-visible spectra. the molar ratio of the metal to the reagent was (1:2).
