Hydroxyurea has the capacity to induce damage to human erythrocytes which can be modified by radical scavengers.
The treatment of human erythrocytes with hydroxyurea [HU] results in the azide-dependent changes in osmotic fragility and in increased methemoglobin formation. Similar changes were induced by H2O2Expand

Modification of catalytic adsorptive stripping voltammetric method of hexavalent chromium determination in the presence of DTPA and nitrate
Abstract.The voltammetric procedure for determination of traces of Cr(VI) [Anal. Chim. Acta (1992) 262:103] was modified by changing the temperature of the measurements. It was found that at theExpand

Voltammetric determination of Cr(VI) in a flow system in the presence of diethylenetriaminepentaacetic acid (DTPA) following its deposition in the metallic state
Abstract A sensitive and very selective procedure for voltammetric determination of traces of Cr(VI) in the flow system is presented. The calibration graph is linear from 1×10−9 to 1×10−7 mol l−1 andExpand
