“…The simultaneous determination of the same analytes with on-line TSK-gel SAX column separation was described by Narusawa [76] in standard solutions. The same column was used by Narusawa et al [77] for simultaneous determination of silicon and phosphorus in ashes of biological standard materials (bovine liver, chlorella and pepper bush). Devi and Townshend [78] proposed a method for nitrate determination based on the desplacement of thiocyanate from an anion-exchange minicolumn and further detection after its reaction with Fe(III).…”

Flow injection analysis (FIA) has emerged as an increasingly used laboratory tool in chemical analysis. Employment of the technique for on-line sample treatment and on-line measurement in chemical process control is a growing trend. This article reviews the recent applications of FlA. Most papers refer to on-line sample treatment. Although FIA is very well suited to continuous on-line process monitoring, few examples have been found in this areamost of them have been applied to water treatment or fermentation processes.

“…Independently from the method used for the final determination of the phosphorus, extraction and preconcentration are applied in general [, 21,22]. The formation of the phosphovanadomolybdate and the phosphomolybdate complex is commonly used for the spectrophotometric determination of phosphorus in various other matrices, too [31][32][33][34][35][36][37][38][39][40][41]. The absorbance of different heteropoly complexes [15], as phosphovanadomolybdate [-23], phosphomolybdate [26], phosphovanadotungstate [ 15], phosphomolybdotungstate [-27] or phosphotungstate [-- [28][29][30] is measured.…”

Extraction inductively coupled plasma-optical emission spectrometry (ICP-OES) determination of traces of phosphorus in tungsten

et al. 1989

A method for the separation and preconcentration of traces of phosphorus from tungsten was developed. Solid phase extraction of the phosphovanadomolybdate complex performed on a micro-column was applied. Phosphorus was determined by optical emission spectroscopy (OES) with inductively coupled plasma (ICP) excitation. A limit of detection of 0.4/~g/g P with respect to the solid phase is obtained. By directly coupling the extraction/elution step to the ICP instrument a detection limit of 0.06 #g/g P in W was achieved. Besides, the complexity of spectral evaluation in ICP-OES determinations of traces in spectralline-rich matrices is discussed.The determination of traces of phosphorus in highly purified tungsten and tungsten oxides is of major interest in certain fields of technology and production. It is assumed that even low concentrations of phosphorus unfavourably affect the quality of tungsten materials [1,2].An increasing demand exists for pure and ultrapure refractory metal products. To characterize these materials and to control the production process, trace and ultratrace analysis is required. Highly instrumented methods, such as high-resolution mass spectrometry techniques [2][3][4][5] or activation analysis [-6, 7] are applied for ultratrace analysis.
