Abstract

Based on establishing the urea solution concentration, Baume degree sequence value table of different temperature, and getting the Baume' degree sequence value of different urea solution by Baume' hydrometer, the urea solution concentration can be achieved by Baume' degree sequence value table. By means of this method, the accuracy was more than 89.95% as compared with Kjeldahl method, thus being able to offer reference for further improving the method of rapid determination of urea solution concentration. This method was easy to operate with less reagent consumption, high accuracy and rapid speed.
