| 摘 要： | 采用微波密闭消解电感耦合等离子发射光谱法(ICP-AES)对青藏高原土壤-牧草-家畜矿物质系统中无机元素K,Ca,Na,Mg,P,S,Fe,Cu,Mn,Mo,Co和Zn的含量进行了测定,对土壤样品消解采用HNO3-HF-H2O2酸溶体系,而草畜样品消解则采用HNO3-H2O2酸溶体系,以简化实验操作,降低空白值。方法的相对标准偏差均在5%以下,回收率93.5%~113.5%。实验表明该方法具有良好的准确度和精密度,验证了分析数据的可靠性,为研究青藏高原土-草-畜矿物质系统中矿物质元素含量、循环、互作以及在放牧补饲生产中科学运用矿物质元素与添加剂提供了科学依据。 |
| 关 键 词： | 青藏高原 土-草-畜 电感耦合等离子体发射光谱 常量元素 微量元素 |

| Abstract: | The contents of inorganic elements including K,Ca,Na,Mg,P,S,Fe,Cu,Mn,Zn,Mo,and Co in the soil-grass-animal mineral system from Qinghai Tibetan Plateau were determined by ICP-AES using high pressure system-sealed microwave digestion.The sample of soil was digested with HNO3-HF-H2O2 acids system, but others including pasture,animal fur,liver,and serum were digested with HNO3-H2O2 acids system.The operation would be simplified and the blank value would be decreased with the above acids systems.The results were... |
