Abstract
Because of the variable nature of technical titanium(III) sulphate normally used for the determination of nitrate in soil extracts by the Bremner-Shaw microdiffusion method, the possibility of replacing this reagent with iron(II) sulphate was studied. It was found that 1 ml of M iron(II) sulphate (in 0·5 M sulphuric acid)plus 0·1 ml of saturated silver sulphate could be used to successfully determine up to 200 µg of nitrate nitrogen in 5-ml aliquots of soil extracts.Keywords
