| Abstract: | A novel 4-acylpyrazolones compound of 1-(2-pyridyl)-3-methyl-4-trifluoroacetyl-pyrazol-5-one (PMTP) was synthesized.The structure was confirmed by IR,1HNMR,ESI-MS and elemental analysis.The color reaction PMTP and Fe3+ has been investigated in detail.The results showed that the PMTP has highly selectivity for Fe3+ in the chromogenic reaction.The absorbance (A) of the complex had good linear relationship with the contents of Fe3+ from 0.18～1.8 μg/mL.The liner regression equation was A =0.423ρ-0.020(μg/mL) with a detection limit of 0.064 μg/mL(n =11) and the linear correlation coefficient was 0.999 3. |
