“…Emission spectroscopy is a sensitive and specific method for the determination of Al in almost any type of material (34)(35)(36)(37). Preparation and manipulation of the sample are kept Environmental Health Perspectives to a minimum to reduce the possibility of contamination that is often encountered in other procedures.…”

The review of over 800 references on aluminum (Al) published since the mid-fifties covers the occurrence of Al in soil, air, water, plants and food products, as well as air and water pollution problems. In addition, the existing quality criteria, the biology and toxicology of Al, and the therapeutic and medical uses are presented. It is concluded that absorption and retention or accumulation of Al in humans occurs at lower levels of intake than had been assumed formerly. However, levels of 5 to 50 times the normal daily intake do not appear to interfere with other metabolic processes. The adverse effects of Al reported in the more recent years resulted from the inhalation or ingestion of Al in concentrations many times greater than the amounts present under normal circumstances. As in the past, there is still no need for .ncern by the public or producers of Al or its products concerning hazards to human health derived from well established and extensively used products.

“…Direct reading spectrographs are now used in place of the time-consuming photographic plate method (34,35). Absolute detection limits of 106 to 108 g are regularly reported for Al (23,35,37) (absolute detection limits meaning minimum detectable amounts introduced to arc).…”

“…This metal is widely distributed in the earth's crust but in low abundance.Major sources for the emission of vanadium in the environment include combustion of fuel oils, dyeing, ceramics, ink, catalyst and steel manufacturing.Vanadium in trace amounts represents an essential element for normal cell growth, but it can be toxic when present in higher concentrations 7 . A variety of methods have been used for determination of vanadium; these include fluorometry 8 , gaschromatography 9 , neutron activation analysis 10,11 , x-ray fluorescence spectrometry 12 , emission spectroscopy 13 and atomic absorption spectroscopy 14 kinetic method 15 . These methods either lack sufficient sensitivity or are time consuming.…”

Abstract:A new, simple, sensitive and selective kinetic spectrophotometric method was developed for the determination of ultra trace amounts of vanadium(V). The method is based on the catalytic effect of vanadium(V) on the oxidation of malachite green oxalate (MG) by bromate in acidic and micellar medium. The reaction was monitored spectrophotometrically by measuring the decrease in the absorbance of malachite green oxalate (MG) at 625 nm with a fixed-time method. The decrease in the absorbance of MG is proportional to the concentration of vanadium(V) in the range of 1-100 ng/mL with a fixed time of 0.5-2 min from the initiation of the reaction. The limit of detection is 0.71 ng/mL of vanadium(V). The relative standard deviation for the determination of 5, 30, 50 ng/mL of vanadium(V) was2.5% 2.6%, 2.4% and respectively. The method was applied to the determination of vanadium(V) in water samples.

Kinetic-catalytic spectrophotometric methods were proposed for the determination of trace amounts of vanadium element as vanadium(IV) and/or V(V) ions. The vanadium(IV) as VO 2＋ ion and/or vanadium(V) as 3 VO -ion showed a catalytic effect on the kinetic reactions between a color reagent such as methylthymol blue (MTB) or SPADNS and bromate in acidic media. The rate of decrease in the absorbance of the reagent MTB at 440 nm or SPADNS at 510 nm was proportional to concentration of V(IV) and/or V(V) ions in the solution. The linear ranges for determination of vanadium were obtained in the range of 1.0-150 and 5.0-100.0 µg/L by the fixed-time and slope methods, respectively, with using MTB as reagent. In the presence of SPADNS as reagent, the calibration curves were made in the amplitude 1.0-200.0 and 5.0-150 µg/L of vanadium ion by the fixed-time and slope methods, respectively. Using fixed-time method, the limits of detection were obtained to be 0.5 and 0.7 µg/L of vanadium in the presence of MTB and SPADNS as reagents, respectively. Detection limits of vanadium by slope method and reagents of SPADNS and MTB were obtained to be 3.5 and 3.8 µg/L of vanadium, respectively. The proposed methods were applied successfully to determination of vanadium in synthetic and real samples.
