[Flow-injection chemiluminescence determination of trace copper on-line separation and enrichment by ion imprinted polymer].

In the present study, Cu(II)-imprinted polymer was prepared and used as an effective method for separation and enrichment of Cu (II) ion in samples. An on-line preconcentration and extraction flow-injection system using solid phase extraction (SPE) column packed with prepared ion imprinted polymer (IIP) was set up. The column was eluted with a mixture of ethanol and H2 SO4 after preconcentration.

[Study on the determinations of Ni, Fe, Mo, Mn and B in Ti/TiC composite material by atomic emission spectrometry].

The present paper describes the determination of trace Ni, Fe, Mo, Mn and B in Ti/TiC composite material using carbon powder, calcium carbonate, cupric oxide and beryllium oxide-as buffer by atomic emission spectrometry (ASE). Be 298.61 nm was selected as internal standard line.

[Determination of ten trace rare earth elements in the sample by atomic emission spectrometry].

This paper describes the determination of trace La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Yb and Lu in the sample, using carbon powder, potassium sulfate, barium sulfate, strontium sulfate, and scandium chloride as buffer, by atomic emission spectrometry (AES). Scandium was selected as internal standard line. Sample separation and chemical treatment were not required.
