The use of chemically modified XAD-4-1,2-bis (o-aminophenylthio) ethane chelating resin for preconcentrating Cr6+, Mn2+, Fe3+, Co2+, Cu2+, Cd2+, Zn2+, Pb2+, and Ni2+ was studied using flame atomic abs...
摘要 A procedure for preconcentration of Mn(II), Fe(II), Co(II), Cu(II), Cd(II), Zn(II), Pb(II) and Ni(II) based on retention of their complexes with 8-hydroxyquinoline (HQ) on Amberlite XAD-2000 resin ...
A procedure for the separation and preconcentration of trace amounts of copper is proposed. It is based on the adsorption of copper(II) ions solution onto a column of Amberlite XAD-2 resin loaded with...
A sensitive and simple enrichment method using microorganisms as an adsorbent is described for the determination of trace manganese in alloys. Manganese was determined by flame atomic absorption spect...
A simple and sensitive solid phase extraction procedure on Amberlite XAD-1180 resin is presented for the determination of chromium, cobalt, manganese and nickel at trace levels by atomic absorption sp...
