Abstract: Detection reagent is formed by reacting a catalyst and xanthydrol. The catalyst includes an active component loaded on a support, wherein the active component includes Pt, Ru, Rh, or a combination thereof, and the support includes carbon material, silica, alumina, or calcium carbonate. The detection reagent can be used to detect the primary amide compound.

Abstract: A method and device for detecting urea are provided. The method for detecting urea includes the following steps. A derivatization reagent reacts with a sample to obtain a mixture, wherein a reaction time period for reacting urea in the sample with the derivatization reagent to form a derivative product is controlled. The derivative product is separated from the mixture. The amount of separated derivative product is analyzed to determine the concentration of urea in the sample.
