METHOD FOR QUANTIFYING THE AMOUNT OF AMMONIUM BICARBONATE IN A SOLID SAMPLE OF AMMONIUM CARBAMATE

摘要

A method for quantifying the amount of ammonium bicarbonate in a solid sample of ammonium carbamate is provided. The method includes measuring the FT-IR spectrum of the sample, calculating the IR band maximum for a first band that is common to ammonium carbamate and ammonium bicarbonate and for a second band that is unique to ammonium carbamate, calculating a ratio of the maximum of the second band to the maximum of the first band, and calculating the concentration of ammonium bicarbonate in the sample from a calibration curve.
