Adsorption and desorption of copper(II) ions onto garden grass.
The garden grass (GG) was firstly used to remove copper(II) from water as bioadsorbent. From the results of characterisation, the GG had the merits of high specific surface area, significant adsorption sites and functional groups. Copper-adsorption significantly depends on the initial copper concentrations, contact time, pH, adsorbent doses, particle sizes and temperature. The positive values o...
متن کاملResistance to cadmium ions and formation of a cadmium-binding complex in various wild-type yeasts.
The resistance to cadmium ions (Cd-resistance) and possible formation of cadmium-binding complexes were examined in eight different wild-type yeasts. Saccharomyces exiguus, Pichia farinosa, Torulaspora delbrueckii and Schizosaccharomyces octosporus exhibited partial Cd-resistance, as compared to the Cd-resistant strain 301N and the Cu-resistant but Cd-sensitive strain X2180-1B of Saccharomyces ...
متن کاملDegradation of ampicillin in the presence of cadmium (II) ions.
Cadmium (II) ion-catalyzed degradation of ampicillin in methanol at 20 degrees C has been studied. It has been observed that the rate values tend to saturate when the concentration of ampicillin or the metal ion is increased. The results obtained in the present study suggest that ampicillin degradation occurs through the formation of a 1:1 (SM) and 2:1 (S(2)M) ampicillin-metal complexes. These ...

متن کاملActivation of mitochondrial glycerol 3-phosphate dehydrogenase by cadmium ions.
Mitochondrial glycerol 3-phosphate dehydrogenase (EC 1.1.2.1.) requires Ca2+ ions for its activity. Cadmium ions also have activatory effect on the enzyme. They activate the glycerol 3-phosphate dehydrogenase in a very narrow concentration range (1-2 mmol/l). As contrasted with calcium, strong inhibitory effect occurred at higher concentrations (3-4 mmol/l). The inhibition induced by cadmium io...
