摘 要:采用氣相色譜法分離單乙醇胺廢液中單乙醇胺和其它雜質(zhì)。方法采用HP-5色譜柱,標準曲線(xiàn)外標法測定單乙醇胺含量。單乙醇胺在1.61~17.73 mg/mL濃度范圍內與峰面積呈線(xiàn)性關(guān)系,回歸方程:y=0.277 6x-66.526 4,相關(guān)系數為0.999 8。平均回收率為99.20%,RSD為0.65%(n=6)。此方法簡(jiǎn)單、準確,便于單乙醇胺廢液中單乙醇胺含量的測定。 |

Abstract:An efficient GC method for the determination of MEA and other impurities in waste monoethanolamine solution was established with HP-5 column based on external standard calibration curves. The linear range of the method was from 1.61 to 17.73 mg/mL for MEA. The regression equation was y=0.277 6×x-66.526 4 with r=0.999 8. The average recovery was 99.20% with RSD 0.65% (n=6). |
Key words:gas chromatography;monoethanolamine;waste solution |
