1. Furthermore, the peak of 3278 cm -1 represents the position of N-H stretching, while the peaks of 1638 cm -1 , 1546 cm -1 , and 1242 cm -1 indicated the positions of the amide group. The peak of 1450 cm -1 represented the position of -COO-stretching. The absorption at these positions indicated the presence of GE as a component [22]. When considering urea, the absorption peak of 1459 cm -1 represented the position of C-N stretching, 3429 cm -1 represented the position of N-H stretching, and 1675 cm -1 represented the position of C=O stretching (Rajendran, 2011). Subsequently, the samples with urea added in quantities of 1;O-H Stretching ; Sethi;FT-IR spectra of urea,2019
