[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.

[Atomic emission spectrometry determination of Au, Pt and Pd after separation and enrichment by hyperbranched polymer].

The present paper shows that the trace amount of gold, platinum and palladium in hydrochloric acid solution can be concentrated by hyperbranched polymer. The new reagent has a rapid adsorption rate and big concentrating capacity. The determination of trace Au, Pt and Pd in sample using carbon powder and strontium carbonate as buffer was carried out by atomic emission spectrometry(AES).

[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.

[Determination of trace zirconium and hafniumin sample by atomic emission spectrometry].

This paper describes the determination of trace Zr and Hf in the sample using carbon powder and titanium oxide as the buffer by Atomic Emission Spectrometry (AES). Titanium was selected for the internal standard line. Sample separation and chemical treatment were not required.
