PMID: 16226764
J Colloid Interface Sci. 2006 Apr 01;296(1):292-308. doi: 10.1016/j.jcis.2005.09.018. Epub 2005 Oct 14.

In the topological approach to structure-property relationships, the molecular structure is described in terms of appropriate weighted graphs to which suitable topological parameters, usually known as molecular connectivity indices, can be associated. Molecular connectivity indices are here applied to...

Determination of beryllium in natural and waste waters using on-line flow-injection preconcentration by precipitation/dissolution for electrothermal atomic absorption spectrometry.

Talanta. 2000 May 31;52(1):27-37. doi: 10.1016/s0039-9140(99)00337-9.

A flow injection (FI) on-line precipitation-dissolution was developed for electrothermal atomic absorption spectrometry (ETAAS) determination of (ultra)trace amounts of beryllium in water samples. Beryllium was precipitated quantitatively with NH(4)OH+NH(4)Cl and collected in a knotted tube of Tygon without using...
