Implication

Analytical study demonstrates sensitive nitrate quantification via titanium(III) reduction and gas-phase ultraviolet spectrometry, highlighting a selective room-temperature detection method.

Key Points

Develop a rapid, sensitive, and selective analytical method for nitrate determination using room-temperature chemical reduction and gas-phase ultraviolet absorption spectrometry.
Nitrate is reduced to ammonia in solution by reaction with titanium(III) sulphate at room temperature.
An air current displaces the generated ammonia into an optical cell to measure molecular absorbance in the ultraviolet gas phase.
Titanium(III) sulphate rapidly converts nitrate to ammonia at room temperature, providing a sensitive and selective measurement system.
Co-existing ions that inhibit or alter the titanium(III) reduction mechanism produce analytical interference and require removal when present in high concentrations.
