Methods for determining metal ion leaching from glass cullet using Flame Atomic Absorption Spectroscopy

Methods compared for determining zinc in serum by flame atomic absorption spectroscopy.

We compared two methods for determination of serum zinc by flame atomic absorption spectroscopy. The first involved 10-fold dilution of serum with water; the second, deproteinization of serum with trichloroacetic acid. Analytical recovery of Zn2+ added to serum averaged 99.3 and 99.9%, respectively, by the two methods, but measured concentrations were consistently greater by the second method [...

MONITORING OF LEAD POISONING IN SIMPLE WORKERS OF A COPYING CENTER BY FLAME ATOMIC ABSORPTION SPECTROSCOPY

Inorganic lead compounds are used most widely in paint and pigment industries. Because of exposure to lead dust in workers in a copying center, we compared blood lead levels in these workers to normal individuals and investigated the relationship between job tenures of the workers and their blood lead levels. This survey was performed on 20 simple workers in a copying center of Tehran Univ...

Spectrophotometric determination of Dalacin phosphate from formulations using reduce atomic absorption of calcium ion by phosphate

A simple, sensitive and accurate method for spectrophotometric determination of Dalacinphosphatehas been established. The method is based on the reduction of atomic absorptioncalcium ion by phosphate. Because, there is a phosphate mole in every Dalacin mole structureand with measurement of phosphate, Dalacin is beyond measurement too. Therefore, the reactionbetween acidic hydrolysis products of...

Simplification of Metal Ion Analysis in Fresh Water Samples by Atomic Absorption Spectroscopy for Laboratory Students

Metal ion analysis is an important aspect during water quality monitoring of either surface or ground water sources. In spite of the availability of several other metal ion analysis techniques for drinking water samples, today atomic absorption spectroscopic (AAS) method is most commonly being used due to the reproducibility of results, short analysis time, cost effective, lower level detection...
