“…3). Barium emission intensity decreased with increasing sodium or magnesium concentration due to physical interference as already reported by Sugimae (1979) but significant shift in the background signal by stray light was not detected. In addition, the effects of K, Ca, Sr, Li, Rb, B, P, Si, Fe and A1 were also investigated.…”

“…Inductively coupled plasma emission spectrometry (ICP-ES) which has been developed rapidly in recent years has many advantages, for example, its high sensitivity for most elements (Winge et al, 1979) and large dynamic range (McQuaker et al, 1979) and has recently been applied to analysis of samples from various environments: river water (Sugimae, 1979;Miyazaki et al, 1982), sea water (Miyazaki et al, 1982), waste water (Sugimae, 1979;Nojiri et al, 1981), soil (McQuaker et al, 1979, and marine sediment (McLaren et al, 1981).…”

Abstract:A method for the determination of barium in sea water was investigated using inductively coupled plasma emission spectrometry, and sea water samples from the Japan Sea and the Pacific Ocean were directly analyzed by this method. Artificial sea water was used to prepare matrix matched standard solutions to overcome the problem of physical interference. The detection limit (signal/noise ratio = 2) for barium in deionized and distilled water was 0.08/~g1-1 and in sea water, 0.12 /Lg1-1. The reproducibilities in the purified water and in the sea water at the 10#g1-1 level were 0.7% and 0.5°//o, respectively. The barium concentration in both the Japan Sea and the Pacific Ocean increased with deptll and ranged between 5.5-10.0pg1-1 and 4.1-18.4ggI -~, respectively.

“…The solvent used must have a low aqueous solubility but more importantly be compatible with aspirating into the plasma. For this reason, back-extraction into a low volume of dilute acid is preferable when non-suitable solvents, like chloroform, have been used [27].…”

“…Brooks et al 6 determined cobalt, copper, iron, lead, nickel and zinc in saline waters by simultaneous extraction of their ammonium pyrollidine dithiocarbamate (APDC) complexes into methyl isobutyl ketone (MIBK) and subsequent analysis by atomic absorption spectrometry. A procedure for the determination of iron, manganese, copper, zinc, cadmium, lead, vanadium and nickel in sea water was described by Sugimae 7 . In it, the trace elements are complexed with diethyldithiocarbamic acid (DDTC) and extracted with chloroform, followed by a decomposition of the extract and determination by using the ICP-AES technique.…”

O presente trabalho descreve o uso de 1-(2-thiazolylazo)-p-cresol (TAC) para separação, preconcentração e determinação de traços de ferro (ng g -1 ) em sais alcalinos usando a técnica ICP-AES. O método proposto é baseado na extração líquido-líquido do complexo formado entre o cátion ferro(III) e o 1-(2-thiazolylazo)-p-cresol (TAC). Foram estudados parâmetros tais como: quantidade de TAC, efeito de pH, influência do solvente orgânico, mineralização da fase orgânica e re-extração. Os resultados demonstraram que o complexo ferro(III)-TAC, formado na faixa de pH de 4,0 a 10,0, pode ser quantitativamente extraído de soluções salinas, usando como solvente extractor álcool isoamílico, tetracloreto de carbono, clorofórmio ou metil isobutil cetona. A solução para determinação de ferro pode ser obtida por uma re-extração usando soluções de ácido clorídrico 1 mol/L ou ácido nítrico 1 mol/L ou também por uma mineralização da fase orgânica, com uma evaporação do solvente orgânico e digestão do resíduo com ácido nítrico concentrado. O procedimento foi usado para determinação de ferro em amostras de vários sais alcalinos. A técnica da adição padrão foi aplicada e as recuperações obtidas revelaram que o procedimento proposto tem uma boa exatidão.The present paper describes the use of 1-(2-thiazolylazo)-p-cresol (TAC) for separation, preconcentration and determination of iron traces (ng g -1 ) in alkaline salts by the ICP-AES technique. The proposed method is based on the liquid-liquid extraction of the complex formed between iron(III) and 1-(2-thiazolylazo)-p-cresol (TAC). Parameters such as: TAC amount, pH effect, influence of the organic solvent on the extraction, back extraction and mineralization of the organic phase were studied. The results show that the iron(III)-TAC complex, formed in the pH range from 4.0 to 10.0, can be quantitatively extracted from saline solutions (up to 30% NaCl) using isoamyl alcohol, carbon tetrachloride, chloroform or methyl isobutyl ketone as extracting solvent. The solution for the iron determination can be obtained by a back extraction using 1 mol/L hydrochloric acid or 1 mol/L nitric acid solutions or also by mineralization of the organic phase, which was accomplished by evaporation of the organic solvent and digestion of the residue with concentrated nitric acid. The procedure was used for iron determination in several alkaline salt samples. The standard addition technique was applied and the recoveries obtained revealed that the proposed procedure has a good accuracy.
