Extractive spectrophotometric determination of molybdenum(VI) using 3-hydroxy-2-( 4-methoxyphenyl) -6-propionyl-4H-chromen-4-one as a new reagent

摘要: were obtained by suitable dilutions. Solutions of diverse metal ions and anions prepared in deionized water or dilute acid for the interference studies. 3-Hydroxy-2-(4-methoxyphenyl)-6-propionyl -4H-chromen-4-one (HMPC) was synthesized literature method 6 dissolved ethanol to give 0.1% (w/v) solution. Flue dust steel samples as reported earlier 2 • A UV -visible spectrophotometer (Systronics-118) with 1 em matched cells used absorbance measurements.
