A new spectrophotometric method for the determination of trace amounts of titanium(IV)

Abstract

A new, rapid, simple, precise and extraction-free spectrophotometric method is proposed for the micro determination of titanium(IV) employing N'-(2-hydroxybenzylidene)- 3-oxobutanehydrazide as a reagent. Under the optimum conditions established, the absorbance was found to increase linearly with the concentration of titanium(IV) in the range 1.757 to 17.57 μg mL−1. The method parameters such as the molar absorptivity, Sandel sensitivity, stoichiometry of the complex, method detection limit and limit of quantification were reported. The reproducibility of the method was excellent and recoveries reported were ranging from 102 to 104%. The proposed method can be readily applied for the determination of titanium(IV) in synthetic mixtures and alloys

An innovative approach in titanium determination based on incorporating 2-amino-4-((4-nitrophenyl)diazenyl)pyridine-3-ol in a PVC membrane

“…Notably, the achieved molar absorptivity surpasses that of previously reported methods. [63][64][65][66][67][68][69][70][71][72][73][74][75] underscoring the superior performance of our approach. Moreover, our procedure exhibits outstanding selectivity, characterized by impressively low limits of detection and quantication.…”

Heavy Metal Analysis by Spectrophotometric Equation

“…Heavy metals exist as natural constituents of the earth crust and are persistent environmental contaminants, because they cannot be degraded or destroyed (5,7,13). Titanium has its application in several industries ,used for making different alloys, there is a increase use of titanium in different field due to which it become necessary to analyse the titanium metal by simple and sensitive techniques, as several other techniques are reported by literature survey which are highly sophisticated and expensive but spectrophotometric method of analysis are quite simple,rapid ,interference free and cheap technique of analysis of titanium metal (15,16,18). Heavy metals are generally bounded with inert material and concentration of these metals have increased many times because of manmade activities.…”
