| 摘 要： | 用火焰原子吸收分析法,分析聚乙烯及聚丙烯树脂中的微量镁,样品经过灰化,用焦硫酸钾熔融浸取,用氯化锶或氯化镧作稀释剂可消除共存离子铝(5—30微克/毫升)、硅(1—20微克/毫升)等的干扰。镁含量为10~(-4)—10~(-3)％时,标准偏差为0.9—1.1×10~(-4)％。

Analysis of trace magnesium in polyolefin resin by atomic absorption spectrophotometry |
| |
| Abstract: | Trace magnesium in polyethylene and polypropylene was analysed by flame atomic absorption method.The sample after washing was melt extracted with K_2S_2O_7 and diluted with SrCl_2 or LaCl_3 to eliminate the interference caused by coexisted aluminium and silicon.The standard deviation of the method is 0.9—1.1×10~(-4). |
