The electrocatalytic reduction of NO3− in neutral medium was investigated at Cuelectro-deposited Pt electrodes. Inherently, the fabricated Pt–Cu electrode surface contains Cu (I) and Cu (II) oxides. The presence of these oxides decreases the efficiency of the electrode pertaining to nitrate reductio...

A very simple, ultra-sensitive and fairly selective non-extractive spectrophotometric method for the determination of trace amounts of lead with 2,5-dimercapto-1,3,4-thiadiazole (DMTD) has been developed. DMTD reacts in slightly acidic (0.0015-0.01 M HCl) aquatic media with lead(II) to give a greeni...
