✦ Synopsis

AbStrsCt

The workmg conddloons affectmg the kmetlcs of formatlon of the complex between terephthalmonohydroxamlc acid and manganese were studied and ophmlzed and both classical kmetic determmatlon methods and two new methods based on semi-loganthnuc fittings of the non-linear portions of absorbance-tune curves and on theoretical equations descnbmg the kmehcs of the process were used for the detemunahon of microgram amounts of manganese The kinetic methods thus developed and the new eqmhbnum spectrophotometrlc method were applied to the determination of manganese m steels
