DTPA提取土壤样品中Fe元素检测方案(ICP-AES)

使用 Agilent 5110 SVDV ICP-OES 测定DTPA 提取土壤中的营养元素 摘要： The micronutrients Cu， Fe， Mn， Zn， Co， Ni and heavy metals Cd and Pb were analysed in a DTPAextracted soil sample using both a standard Agilent 5110 ICP-OES and a 5110 fitted with anintegrated Advanced Valve System (AVS 6) six port switching valve. The 5110 ICP-OES delivered goodlinearity over a wide concentration range and excellent method detection limits. The method wasvalidated with spike recoveries obtained within ±10% of target values， demonstrating the accuracyof the developed method. The AVS 6 switching valve system reduced sample analysis time and cutargon consumption by almost 50%. 本应用简报介绍了使用 Agilent 5110 ICP-OES 测定 DTPA 提取土壤样品中的微量营养元素 Cu、Fe、Mn、Zn、Co、Ni及重金属 Cd 和 Pb。为比较样品分析时间和氩气消耗量，还使用配备集成式高级阀系统 (AVS 6)六通切换阀的 5110ICP-OES生成结果。 X · Agilent Technologies The micronutrients Cu, Fe, Mn, Zn, Co, Ni and heavy metals Cd and Pb were analysed in a DTPA extracted soil sample using both a standard Agilent 5110 ICP-OES and a 5110 fitted with an integrated Advanced Valve System (AVS 6) six port switching valve.
