Sodium Dibutyldiselenocarbamate. Analytical Application to the Extraction Spectrophotometry of Heavy Metals

Evaluation of Analytical Procedures in the Determination of Trace Metals in Heavy Crude Oils by Flame Atomic Absorption Spectrophotometry

In the present work, four trace metals, V, Ni, Cu and Fe, have been determined in five crude oil samples of Eastern Baghdad area, Iraq by flame atomic absorption spectrophotometry. The crude oils are characterized with API gravity values in the range, 25 15. The V/Ni ratios for the studied crudes were in the range 3.7 to 5.4 and indicated a typical of the sapropelic-type organic matter. The Ni ...

Basic Principles and Analytical Application of Derivative Spectrophotometry

Application of multivariate statistics and geostatistical techniques to identify the spatial variability of heavy metals in groundwater resources

The performance of geostatistical and spatial interpolation techniques for estimation of spatial variability of heavy metals and water quality mapping of groundwater resources in Ramiyan district (Golestan province- Iran) were investigated. 24 spring/well water samples were collected and the concentration of heavy metals (Ni, Co, Pb, Cd and Cu) was determined using Differential Pulse Polarograp...

application of biochemical tests to evaluate the pollution of the unislaw basin soils with heavy metals

to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...
