索氏提取－高效液相色谱法测定底泥中邻苯二甲酸酯

摘要

A method for the determination of phthalic acid esters in sediment samples by using soxhlet extraction couple with High Performance liquid chromatography was established .Linear correlation coefficient was over 0.997 .The limits of detection were 0.003~0.005 μg/g.The relative standard deviations were 0.63 %~2.18%.The recoveries of phthalic acid esters were 85.0 %~103.5 %.%建立了索氏提取－高效液相色谱法分析4种邻苯二甲酸酯类物质，并对实际底泥样品进行了测定。4种邻苯二甲酸酯类化合物的线性回归相关系数均大于0．997，检出限为0．003～0．005μg／g，相对标准偏差为0．63％～2．18％，加标回收率为85．0％～103．5％，准确有效。
