iCAP 6500 等离子体发射光谱仪分析土壤沉积物中金属元素

abstract：

The analysis of trace elements in soils, sediments and other soil-like solid materials is an important application for ICP emission spectrometry. This type of analysis is needed in order to monitor land used for crop growth for nutrient levels and the presence of toxic elements, for the protection of ground water sources from exposure to toxic elements that may leach from soil and to support decisions on future land use and contaminated site clean-up.

Consequently, such analytical data can often guide and support potentially difficult and costly decisions and therefore needs to be robust and rigorously controlled to eliminate the risk of poor decision-making. ICP has been used for the analysis of trace elements in soils and sludges due to its rapid, multi-element analytical characteristics. Acid extractions or digestions are often performed by hotplate, open tube or microwave digestion system and the resulting solution is analyzed by ICP emission spectrometry.

　　Conclusions：

The iCAP 6500 Duo ICP is well suited for the determination of major and trace elements in soils and sludges. The full wavelength coverage of the unique CID detector allowes the optimum wavelength to be selected while the high sensitivity of the axial torch provided the lowest possible detection limits for low concentration elements. The results of the analysis of the certified reference materials show excellent agreement between the measured and certified alues, indicating accurate analysis and freedom from interference at the lines selected. Due to its exceptional nalytical performance, ease-of-use and the versatility of axial and radial plasma viewing, the iCAP 6500 is an ideal ICP for routine soil, sediment or sludge analysis.
