Title: Color reaction of D-(+)-glucose thiosemicarbazone with Fe(III) and its application
Abstract: The color reaction of D-(+)-glucose thiosemicarbazone(HL) with Fe(Ⅲ) was studied.In HAc-NaAc buffer solution(pH 4.2-5.9),Fe(Ⅲ) reacted with HL to form a 1∶2 stable water soluble complex with an apparent molar absorptivity e_(299.1)=6.20×10~4 L·mol~(-1)·cm~(-1).Beer′s law was obeyed in the concentration range of 0.2~16.0 μg/25 mL for Fe?.The method had been applied to the determination of iron in aluminium alloy and pig hair with satisfactory results.
