| 摘要:本研究以丙酮可溶物含量作为评价指标，采用Box-Behnken响应面法对纸浆丙酮可溶物自动索氏提取方法进行优化。结果表明，最优提取参数为提取温度76 ℃、提取时间25 min、提取溶剂体积64 mL。经实验验证，该方法检出限为0.013%，加标回收率>95%，重复性变异系数<5%，再现性变异系数<10%，检测结果满足GB/T 27417—2017要求，表明该方法准确性高、重现性好，满足工业化纸浆生产的质量控制需求，为丙酮可溶物检测提供了更高效可靠的解决方案。 |
| Abstract:This study used the acetone soluble content in pulp as an evaluation index and optimized the Soxtec method using Box-Behnken response surface methodology. The results showed that the optimal extraction parameters were temperature of 76 ℃， time of 25 min， and solvent volume of 64 mL. Through experimental verification， the LOD of this method was 0.013%， the spiked recovery rate was >95%， the coefficient of variation of repeatability was <5%， and the coefficient of variation of reproducibility was <10%. The detection results met the requirements of the GB/T 27417—2017， indicating that this method had high accuracy and good reproducibility， met the quality control requirements of industrial pulp production， and provided a more efficient and reliable solution for acetone soluble substance detection. |
