Comparative Study of Heavy Metals in Soil and Selected

Essential and nonessential heavy metals like iron (Fe), nickel (Ni), manganese (Mn), zinc (Zn), copper (Cu), cadmium (Cd), chromium (Cr), and lead (Pb) were analyzed in four selected medicinal plants such as Capparis spinosa, Peganum harmala, Rhazya stricta, and Tamarix articulata by flame atomic absorption spectrophotometer (FAAS). These medicinal plants are extensively used as

Preconcentration and Determination of Trace Amounts of Heavy

A fast and simple method for preconcentration of Ni2+, Cd 2+, Pb+, Zn2+, Cu2+ and Co2+ from natural water samples was developed. The metal ions were complexed with sodium diethyldithiocarbamate (Na-DDTC), then ad-sorbed onto octadecyl silica membrane disk, recovered and determined by FAAS. Extraction efficiency, influence of

Determination of Cu, Ni, Mn and Zn in diesel oil samples using

As a natural adsorbent, sisal (agave sisalana) fibers were used to extract Cu, Ni, Mn, and Zn from diesel oil samples for posterior determination (i.e., direct analytical measurements on the solid support) of the analytes by energy dispersive X-ray fluorescence spectrometry (EDXRF).In the proposed procedure, 0.2 g of sisal fiber was directly added to 5.0 mL of diesel oil contained in a glass

Modelling of Cd, Cu, Pb and Zn transport in ... - Plant and Soil

The main aim of this study was to validate the HYDRUS-2D model for the simulation of Cd, Cu, Pb and Zn transport within a soil column and their accumulation by willows. A simulation of metal transport and uptake by willow was implemented using the HYDRUS-2D code. Two scenarios of the column experiment were compared: soil (C) and soil with planted willows (V). Seeping water, soil water content

Copper Trafficking in Plants and Its Implication on Cell Wall Dynamics

In plants, copper (Cu) acts as essential cofactor of numerous proteins. While the definitive number of these so-called cuproproteins is unknown, they perform However, Cu excess may exert in contrast detrimental effects on plant primary production and even survival. Therefore it is essential for a plant

Analysis of Polyacrylamide Gels for Trace Metals Using Diffusive

2019. 5. 25. · A simple method for the analysis of polyacrylamide diffusive gradients in thin film (DGT) gels by laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS), employing a novel use of 115In internal standardization, has been developed. This method allows the determination of Co, Ni, Cu, Zn, Cd, and Pb concentrations (at the DGT filter face) or fluxes in sediments at a spatial

Heavy metal (Zn and Cu) complexation and molecular size

The size distributions of zinc and copper species in the effluent of a wastewater treatment plant were determined by a combination of ultrafiltration and chelating disk cartridge fractionation. The results showed that 75–87% of total Zn and 84–86% of total Cu were strongly complexed or particle-bound in the final effluents.
