Bidentate and tridentate heterocyclic azo compounds with and without a long alkyl chain were prepared and examined for cation exchange chromatography of manganese, zinc, and cadmium; these ions could not be separated by reversed phase HPLC following precolumn derivatization with heterocyclic azo compounds owing to the dissociation of the complexes. The newly prepared azo compounds having a long...

A rapid flotation method for separation and enrichment of ultra trace amounts of copper(II), cadmium(II), nickel(II) and cobalt(II) ions from water samples is established. At pH 6.5 and with sodium dodecylsulfate used as a foaming reagent, Cu2+, Cd2+, Ni2+ and Co2+ were separated simultaneously with 2-aminocyclopentene-1-dithiocarboxylic acid (ACDA) added to 1 l of aqueous solution. The propose...

Poly(amide amine) dendrimer with naphthyl units (N8) as a fluorescent chemosensor for metal ions was synthesized. We investigated the metal ion recognition of N8. Large changes in the fluorescence spectra of N8 were observed upon the addition of cadmium and zinc ions.

Behavioural responses of sea bass Dicentrarchus labrax were investigated after exposure to cadmium ions in laboratory-controlled conditions. The aim of this study was to discover whether environmental exposure to cadmium ions inactivates fish lateral line system neuromasts, and to determine the behavioural consequences of such a sensory blockage. For this, fish escape behaviour in response to a...

The development of cadmium resistance in an Indian muntjac cell line has been investigated. The parent cell line is highly sensitive to cadmium ions. Resistance was obtained by continuous growth of cells in low levels of cadmium with stepwise increments. Four cell lines were developed with resistances of between 50- and 200-fold greater than that of the parental line. Early in the development o...

We demonstrate ultrafast coherent excitation of an atomic qubit stored in the hyperfine levels of a single trapped cadmium ion. Such ultrafast excitation is crucial for entangling networks of remotely located trapped ions through the interference of photon frequency qubits, and is also a key component for realizing ultrafast quantum gates between Coulomb-coupled ions.

We report a high-precision measurement of the ground-state hyperfine splitting of Cd ions. This result is vital for an atomic clock based on the cadmium ions to estimate the frequency uncertainty. OCIS codes: (120.3940) Metrology; (300.6520) Spectroscopy, trapped ion.

The toxicity of dissolved cadmium to a variety of marine animals has been found to be related to salinity, with decreased toxicity observed at higher salinities. Recent data from our laboratory have demonstrated that the toxicity of cadmium to estuarine shrimp and larval fish is a function of free cadmium ion concentration, which in turn is controlled by the chloride concentration of the water....

Metalloestrogens are inorganic metal ions that bind to and activate oestrogen receptors. They are implicated in the aetiology of oestrogen-dependent diseases such as cancers of the breast and endometrium as well as endometriosis. Cadmium is one of the most studied metalloestrogens. In this review, scientific evidence for the oestrogenic effects of cadmium is critically evaluated to determine if...

The cadmium content of crystallized horse spleen ferritin, usually about 2% by weight without special treatment, can be substantially decreased by prolonged dialysis against certain chelating agents, chaotropic ions, or weakly reducing anions. For example, neutral bisulphite buffer (2M) removed 95% of the bound cadmium of crystallization without affecting the iron content, and may thus be valua...
