摘要:建立气相色谱法测定有机肥料中水分含量的方法。样品在N,N-二甲基甲酰胺中超声提取,采用porapad-Q多孔高分子小球不锈钢填充柱(1 m×4 mm,177~250 μm)为分离色谱柱,加入甲醇作为内标物,以热导检测器检测,内标法定量。结果表明,样品提取液中水的含量在0.00~77.85 mg/g范围内与色谱峰面积呈良好的线性关系,相关系数为0.999 6。样品测定结果的相对标准偏差为0.79%~3.98%(n=7),加标回收率为95.3%~101.3%。该方法准确度高,重现性好,适用于有机肥料中水分含量的定量分析。 
Abstract:A method was established for determining water content in organic fertilizer by gas chromatography with thermal conductivity detector. The samples were extracted in N, N-dimethyl formamide by ultrasound. The porapad-Q stainless steel chromatographic column packed with porous polymer microsphere(1 m×4 mm, 177-250 μm) was used as the separation column. Methanol was added as the internal standard for detection by thermal conductivity detector. The results showed that the water content had a good linear relationship with chromatographic peak area in the range of 0.00-77.85 mg/g, the correlation coefficient were 0.999 6. The relative standard deviations of determination results of samples were 0.79%-3.98%(n=7), and the recoveries were 95.3%-101.3%. The method has high accuracy and good reproducibility, which is recommended for the quantification of water content in organic fertilizer.
