| Abstract: | The method was established to determine methanol in methylamine manufacturing wastewater by Chromotropic acid spectrophotography. The maxium absorption wavelength was determined and experiment conditions were optimized. The results showed the good linearity was achieved in the range from 0 mg/L to 7.00 mg/L, detection limits 0.07 mg/L, RSD of stanared solution ≤0.9% , recoveries of wastewater samples 98.8% - 101%. |
