Pseudomonads from environmental sources vary widely in their sensitivity to cadmium, but the basis for this resistance is largely uncharacterized. A chromosomal fragment encoding cadmium resistance was cloned from Pseudomonas putida 06909, a rhizosphere bacterium, and sequence analysis revealed two divergently transcribed genes, cadA and cadR. CadA was similar to cadmium-transporting ATPases kn...

The syntheses and structures of five mononuclear zinc and cadmium selone complexes along with a polynuclear cadmium selone 1D chain were described. The mononuclear homoleptic zinc selone complexes were the first examples of structurally characterized zinc(ii) selone complexes. The spectral properties of the zinc and cadmium selone derivatives were investigated. Interesting structural diversity,...

Routine determination of trace metals in complex media is still a difficult task for many analytical instruments. The aim of this work was to compare three electro-chemical instruments [a standard potentiostat (Autolab), a commercially available miniaturized potentiostat (PalmSens) and a homemade micropotentiostat] for easy-to-use and sensitive determination of cadmium(II) and lead(II) ions. Th...

Tris(2-pyridylthio)methane ([Tptm]H) has been employed to synthesize a series of cadmium carbatrane compounds that feature an [N3C] coordination environment. Specifically, [Tptm]H reacts with Cd[N(SiMe3)2]2 to afford [Tptm]CdN(SiMe3)2, which thereby provides access to other derivatives. For example, [Tptm]CdN(SiMe3)2 reacts with (i) CO2 to form {[Tptm]Cd(μ-NCO)}2 and (ii) Me3SiOH and Ph3SiOH to...

In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...

Cadmium sulfide uniform fine particles have been synthesized in soft conditions, at room temperature, using cadmium complex compounds and thioacetamide. The microstructure and morphology of cadmium sulfide were characterized by X ray Diffraction, Transmission Electron Microscopy, High Resolution Transmission Electron Microscopy, and Selected Area Electron Diffraction. The optical properties of ...

In this work for the first time, Fe3O4@SiO2 core-shell nanoparticles functionalized with isatin groups as a magnetic nanosorbent was applied for the simultaneous extraction of trace amounts of cadmium (II). The characterization of this nanosorbentwas studied using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and X-ray diffraction (XRD). The effect of seve...

a chelating resin of polystyrene divinylbenzene resin functionalized by 1-(2-pyridylazo) 2- naphtol (psdvb-pan) has been synthesized and its sorption properties have been investigated for preconcentration and determination of cadmium at μg/l level by flame atomic absorption spectrometry. the procedure is based on the sorption of cd(ii) ions on a minicolumn of synthesized chelating resin. the...

Aim of the study: Green tea catechin possesses antioxidant and free radical scavenging activity which stimulate detoxification system through selective induction or modification of phase I and phase II metabolic enzymes. This study was carried out to assess the antioxidative and antimetalotoxic effect of green tea Catechin against cadmium chloride in mice. Method: Adult Swiss albino mice were i...

The objective of the present work was to evaluate the effect of exogenously applied cadmium on the physiological response of green algae Chlorella vulgaris. The study investigated the long-term effect (18 days) of cadmium on the levels of algae biomass, assimilation pigment composition, soluble protein, oxidative status (production of hydrogen peroxide and superoxide anion), antioxidant enzymes...
