河流沉积物中Cu元素检测方案(ICP-AES)

Elemental analysis of riversediment using the Agilent 4200 MP-AES Introduction The elemental profile of river sediments provides valuable insight into thehealth of a river， as well as the wider environment. Some elements that areessential for the ecology of the river at trace levels e. g. manganese，(copperand zinc， can be toxic at high concentrations. Traditionally， the concentration of elements in river sediments is determinedvia Flame Atomic Absorption Spectroscopy (FAAS). This technique has thedrawback of requiring expensive and hazardous gases such as acetyleneand nitrous oxide and also requires element-specific sample preparation thatadds time and cost to the analysis. The novel Agilent 4200 Microwave Plasma-Atomic Emission Spectrometer (MP-AES) is the ideal alternative for laboratories looking to transition away from FAAS to a higher performance， lower cost and safer technique. MP-AES is a fast sequential， multielement analytical technique that uses amicrowave-induced nitrogen-based plasma for sample excitation. The useof nitrogen eliminates the need for acetylene and nitrous oxide，which can Agilent Technologies
