摘要: |
目的 建立三层共挤输液用袋材料中镁残留量及输液袋中镁迁移量的微波消解-火焰原子吸收分光光度法。方法 采用微波消解对样品进行消解处理,以火焰原子吸收光谱法测定样品中镁含量。结果 镁在0~0.30 μg·mL-1内呈良好的线性关系(r=0.995 2);镁含量测定的平均回收率为95.95%(RSD=2.27%)。结论 该方法准确、灵敏、简便,适用于对三层共挤输液用袋材料中镁残留量及镁向输液中迁移量的测定。 |

Abstract: |
OBJECTIVE To develop a method for determination of mg and Mg migration into infusion of 3-layer co-extrusion bags by microwave digestion FAAS. METHODS The sample was digested by microwave digestion. Using FAAS to determine the content of mg. RESULTS The method had a linear range between 0-0.30 μg·mL-1(r=0.995?2). The average recovery of mg was 95.95%(RSD=2.27%). CONCLUSION The method is accurate, sensitive, simple, and can be used for determination of mg and mgmigration into infusion of 3-layer co-extrusion bags. |
