MICRODETERMINATION OF NITRATES AND NITRAMINES .I. TITRIMETRIC METHODS BASED ON REDUCTION WITH IRON(II), TITANIUM(III), AND A MIXTURE OF BOTH

Organic and inorganic nitrates are satisfactorily determined on the microscale by reduction with Fe(II). Titanium(III) reduces the nitrates in strongly acidic, citrate-buffered, and acetate-buffered media with the comsumption of 3, 6 and 8 equivalents respectively of Ti(III) per nitrate group. Nitramines are determined by reduction with a mixture of Ti(III) and Fe(II). Determination of nitrates and nitramines by trans-nitration with salicylic acid is suitable on the microscale. A new electrolytic reduction automatic microburette was devised for the reduction, storage and use of the titanium(III) solution. © 1969.
