“…Nickel concentrations of one ppm are deadly to aquatic environment (Allway, 2000). Nickel leads to a lack of growth, it has effects on the blood (high number of red blood cells), affects the production of protein in the kidneys (Gupta et al, 2002) and affects plant life through its influence on the solubility of ion exchange in plants (Allway, 2000). The results in table 6 indicate that, based on the correction coefficient r, RSD%, Erel and Re%, the atomic absorption method is more accurate and sensitive to the estimation of nickel ions than spectral methods for all the measured samples.…”

“…The results in table 9 indicate that, based on the correction coefficient r, RSD%, Erel and Re%, the spectral method is more accurate and sensitive to the estimation of nickel ions than the atomic absorption method for all the measured samples. This is due to the oxidation of iron (Fe +2 ) to (Fe +3 ) by air within the atomic absorption oven which leads to an overlap in the absorption pattern, giving a lack in accuracy of this method for this element (Gupta et al, 2002). …”

The textile industry is a key source of pollution in fresh water. The concentration of key heavy metal pollutants (cobalt, nickel, lead, mercury, cadmium, copper, and iron) as well as pH value and conductivity were measured in water samples taken from the input and output (waste water) of Al-Diwani textile factory on the Al-Diwani River, Iraq. These samples were measured using two methods, flame atomic absorption spectrophotometry and spectrometry. This paper considers the relative effectiveness of each method for measuring the concentrations of the elements, and discusses which method is best for which element. It was found that the first method is more accurate for measuring the concentrations for all elements except iron. RÉSUMÉ:La détermination par des méthodes spectroscopiques de la pollution dans les eaux de la rivière de Al-Diwani avec certains éléments-trace provenant de l'usine textile de Al-Diwani.L'industrie textile est une importante source de pollution de l'eau douce. La concentration des polluants de la catégorie des métaux lourds (cobalt, nickel, plomb, mercure, cadmium, cuivre et fer), ainsi que le pH et la conductivité ont été mesurés dans des échantillons d'eau pris à l'entrée et à la sortie (eaux usées) de l'eau dans l'usine textile AlDiwani située sur la rivière Al-Diwani en Iraq. Les concentrations des éléments mentionnés cidessus ont été déterminées par deux méthodes: la spectrophotométrie d'absorption atomique sur flamme et la spectrométrie. Cet article se penche sur l'efficacité relative de chaque méthode pour déterminer les concentrations des éléments et discute quelle est la meilleure méthode pour chaque élément. Dans le cas de tous les éléments, sauf le fer, la première méthode a été prouvée comme plus précise pour mesurer les concentrations. REZUMAT:Măsurarea prin metode spectroscopice a nivelului de poluare a apelor râului Al-Diwani cu anumiți contaminanți proveniți de la fabrica de textile Al-Diwani.Industria textilă este o sursă importantă de poluare a apei dulci. Concentrația poluanţilor din clasa metale grele (cobalt, nichel, plumb, mercur, cadmiu, cupru şi fier) precum şi pH-ul şi conductivitatea au fost măsurate în probe de apă recoltate la intrarea şi ieşirea folosinţei de apă a fabricii de textile Al-Diwani, situată pe râul Al-Diwani din Irak. Probele au fost determinate prin două metode: spectrofotometria prin absorbţie atomică pe flacără şi spectrometria. Prezentul studiu analizează eficacitatea relativă a fiecărei metode în măsurarea concentraţiilor elementare şi discută adecvarea fiecărei metode pentru fiecare element. S-a concluzionat că prima metodă prezintă o precizie mai bună pentru măsurarea concentrațiilor tuturor elementelor analizate cu excepția fierului. INTRODUCTIONWater was and still is important for life and human society (Moyle and Leidy, 1992;Curtean-Bănăduc et al. 2007), and it is vital to industry, being used in industrial processes either directly, or indirectly (Nemerow, 1971;Zhou and Smith, 2002). Many rivers form important surface water source...

N(2-Thiophenyl)-1-(2-hydoxyphenyl)Imine (NTPHPI) was used as a proper complexing agent for the preconcentration by cloud point extraction followed by atomic absorption spectrometric to determine of Ni 2+ , Cu 2+ and Co 2+ ions in real samples. NTPHPI and Triton X-114 were used as hydrophobic ligand and non-ionic surfactant respectively and the pH of 8 was chosen as optimum. Under the optimized experimental conditions, the selective preconcentration and determination of low concentration of Ni 2+ , Cu 2+ and Co 2+ ions as 1, 5 and 6 ng mL -1 can be made respectively. The proposed method was successfully applied to the preconcentration and low-level determination of the cited ions in different water, chocolate and honey samples.

Data on the synthesis, complexing ability, practical applications, and biological activity of dibenzotetraazamacroheterocycles of the azacrown ether, amide, and azomethinedibenzotetraazacycloalkane types and also dibenzotetraazamacroheterocycles containing amide and azomethine fragments are classified and analyzed.At present the chemistry of nitrogen macrocycles is developing at a very high rate. Many of the compounds are highly effective extractants for metal ions [1-3], find widespread use as contrast agents for magnetic resonance imaging [4][5][6][7][8], and can also be used as precursors in the biosynthesis of certain types of alkaloids [9] and also as ion-selective [10] and fluorescent [11] receptors and as agents for the transport of ions through a liquid membrane in dialysis and electrodialysis [12,13]. Chiral macrocyclic tetraamides are used as stationary phase in liquid chromatography [14]. The potentialities of nitrogen macrocycles in theoretical and practical respects have not been exhausted, and further research in the field is promising.In the last 15 years there have been a fairly large number of monographs and reviews in which aspects of the synthesis, properties, and applications of azamacroheterocycles and their metal complexes have been touched upon [15][16][17][18][19][20][21][22][23][24][25][26]. However, there have been significantly fewer publications devoted to the various classes of dibenzotetraazamacroheterocycles (e.g., dibenzotetraaza [14]annulenes [27][28][29], macrocyclic Schiff bases based on 2,6-diformylphenols [30]). Dibenzotetraazamacroheterocycles have found use as effective extractants for metal ions and as spectrophotometric agents [31][32][33], are used in the design of new magnetic materials [34], etc. To fill the gap we considered it desirable to analyze existing published material on the synthesis, complexation, and practical applications of dibenzotetraazamacrocycles of the azacrown ether, amide, azomethine, and dibenzotetraazacycloalkane types and also dibenzotetraazamacrocycles containing amide and azomethine fragments.
