| 中文摘要: |
| 建立了变色酸比色测定甲胺生产废水中甲醇的方法, 确定了最大吸收波长, 优化了试验条件。方法在0 mg/L～7.00 mg/L 范围内线性良好, 检出限为0.07 mg/L, 标准溶液测定的RSD ≤ 0.9% , 废水样品的加标回收率为 98.8%～ 101% 。 |
| 英文摘要: |
| The method wasestablished to determine methanolin methylamine manufacturing wastewaterbyChromotropic acid spectrophotography. The maxium absorption wavelength wasdetermined and experimentcondi tions were optimized. The results showed the good linearity was achieved in the range from 0 mg/L to 7.00 mg/L, detection limits0.07 mg/L, RSD ofstanared solution ≤ 0.9% , recoveriesofwastewatersamples98.8% ～ 101 %. |
