The unique potentiometric response of mercury sensors was investigated in aqueous Cl(-)-rich media, which are often encountered in natural, especially biological samples. The conventional neutral-carrier-based Hg(II)-ISEs are not practically useful because the Cl(-) concentrations in natural aqueous samples are normally too high for mercury to be present in the form of Hg(2+). Negative potentio...

A study on room temperature Suzuki cross-coupling in an aqueous medium was carried out using a simple hydrophilic palladium (II) complex, trans-PdCl2(NH2CH2COOH)2 as catalyst in the presence of K2CO3 in air. This approach with a comparatively inexpensive and hydrophilic catalyst, mild reaction condition and aqueous media exhibits excellent catalytic activity towards the Suzuki coupling of aryl ...

The removal of Pb(I1) ions from aqueous solutions of perchlorate, nitrate, tetrafluoroborate, chloride and sulfate, pH 2, has been investigated in a cell with a reticulated vitreous carbon cathode. It is confirmed that the Pb(II) may always be removed. There are, however, marked differences in the conditions necessary and the performance attained by the system (eg, rate of removal, current effi...
