| Abstract: | Based on the laser Raman scattering theory,the characteristic peak(892cm-1) of acetic acid was acquired,so a new determination method for the acetic acid was established using the nitric acid as the internal standard substance.There was a good linear relationship between the acetic acid and the relative intensity in the range of 1%～60%,the linear regression equation was I=4.4886x+0.34312,the correlation cofficent was 0.9997,the recoveries of standard addition was 96 % ～ 107 % and the relative standard deviation were 0.57%、0.42%、0.33% respectively. |
