Preconcentration and Determination of Trace Amounts of Heavy Metals in Water Samples Using Membrane Disk and Flame Atomic Absorption Spectrometry
preconcentration atomic absorption spectrometry
2007/12/20
摘要 A fast and simple method for preconcentration of Ni2＋, Cd2＋, Pb2＋, Zn2＋, Cu2＋ and Co2＋ from natural water samples was developed. The metal ions were complexed with sodium diethyldithiocarbamate (Na...
Determination of Pb(II) and Cu(II) by Electrothermal Atomic Absorption Spectrometry after Preconcentration by a Schiff Base Adsorbed on Surfactant Coated Alumina
determination of lead and copper preconcentration
2007/12/20
摘要 1,2-Bis(salicylidenamino)ethane loaded onto sodium dodecyl sulfate-coated alumina was used as a new chelating sorbent for the preconcentration of traces of Pb(II) and Cu(II) prior to atomic absorpt...
