Diphenylcarbazone has been used for the simultaneous and individual determination of zinc(II) and cadmium(II) at trace levels. The carbazone complexes of zinc(II) and cadmium(II) at pH 7–10 are pink in color, and are soluble in TX-100 micellar media. Under optimum conditions, calibration graphs for individual and simultaneous determination by first, second, third and fourth derivative spectroph...

Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...

The objective of the current study was to explore the inhibitory effects of quercetin on cadmium-induced autophagy in mouse kidneys. Mice were intraperitoneally injected with cadmium and quercetin once daily for 3 days. The LC3-II/β-actin ratio was used as the autophagy marker, and autophagy was observed by transmission electron microscopy. Oxidative stress was investigated in terms of reactive...

a selective and sensitive method for determination of cadmium and zinc is presented. the method is based on adsorptive accumulation of the complexes of cd (ii) and zn (ii) ions with 4-amiono-5-methyl-2,4-dihydro-3h-1,2,4-triazol-3-tion (mmtt) onto hanging mercury drop electrode (hmde), followed by reduction of the adsorbed species by voltammetric scan using differential pulse modulation. the li...

Experimental data on cadmium (II) and nickel (II) ion sorption on deactivated protonated yeast over a wide range of sorbent and initial metal concentrations, were analyzed by an equilibrium model based on a thermodynamics approach. Model describes relationships between the equilibrium concentration of metal, metal sorption per unit biomass dosage and concentration of sorbent and initial metal c...

The Schiff bases (H3L), derived from 2-acetylpyrrole and carbonohydrazide, and its reactions with some transition metal ions (Co(II), Ni(II), Cu(II), Zn(II) and Cd(II)) afforded complexes of formulae [M(H5LA)2(H2O)x]∙2(NO3)∙(CH3CN)z∙(H2O)y-x (M= Co, Ni, Cu or Zn ; 0 ≤ x < y ≤ 3, z = 0 or 1) and {Cd(H4LA)(NO3)}n. These compounds have been characterized by means of elemental analysis, UV–Vis spec...

Compounds of nickel(II) and cadmium(II) are carcinogenic to humans and to experimental animals. One frequently discussed mechanism involved in tumor formation is an increase in reactive oxygen species by both metals with the subsequent generation of oxidative DNA damage. In the present study we used human HeLa cells to investigate the potential of nickel(II) and cadmium(II) to induce DNA lesion...

The aim of the present study was to establish to what degree a one-year exposure of rat females to 5, 50 and 100 mg Cd/l affects the weight of the submandibular glands and their cadmium levels. We observed a decrease in the weight of the submandibular glands in the rat females from Groups I, II and III, compared to the control rats. We also found an increase in cadmium levels in the submandibul...
