ABSTRACT:
A method for determining a urea concentration in an aqueous solution containing urea, includes: hydrolyzing the urea in the aqueous solution, measuring an electric conductivity χ of the aqueous solution, and determining the urea concentration in the aqueous solution from the electric conductivity χ using a correlation between the urea concentration and an electric conductivity.
