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) i

Electrochemical studies of certain 1-(toluenyl sulfonyl )-3- amino -4-(4’-substituted aryl hydrazono )-2-pyrazolin -5-ones

The electrochemical behavior of certain1-(Toluenyl sulfonyl)-3-amino-4-(4’-substituted aryl hydrazono)-2-pyrazolin-5-ones were studied at the droppingmercury electrode by employing DC polarography.The variables that influencethe electrode process were extensivelystudied. All compounds under investigationgave two well-defined polarographicwaves. The mechanism for the electrodeprocess was proposed in acid as well asin basic media
