摘　要:對原子吸收分光光度法測定土壤中銅元素含量的不確定度進(jìn)行評定,分析其不確定度的主要影響因素。結(jié)果表明影響其測量不確定度的主要原因是由標(biāo)準(zhǔn)溶液引入的不確定度、標(biāo)準(zhǔn)曲線引入的不確定度和重復(fù)測量引入的不確定度。[著者文摘]

Uncertainty of Determination Copper in Soil with Flame Atomic Absorption SpectrometrySHEN Rong-rong, CHEN Zhi-xiang, SHA Yue-taoShanghai Luwan Environmental Monitoring Station, Shanghai 200020, ChinaAbstract:The determination of uncertainty of copper ion in soil using flame atomic absortion spectrophotometry was introduced.The determination uncertainty of copper ion in soil mainly came from the standard solution,the labor curve and the repetitive measurement.[著者文摘]
