Folic acid is of biological origin and occurs ubiquitously in the natural system. Very little is known about its likely occurrence and distribution in natural waters. A voltammetric method is proposed to determine folic acid in sea and estuarine waters. The method is based on cathodic stripping volt

The effects of the potential scan speed on the adsorptive cathodic stripping voltammetric determination of zinc-tetramethylenedithiocarbamate complexes in sea water were investigated. It was observed that an increase in scan speed increases the peak height and peak width, shifts the peak potential t
A sensitive and selective adsorptive stripping voltammetric method was employed to determine traces of tin in water samples. The spontaneously formed tin complex with 2,5-dichloro-1,4-dihydroxy-3,6-benzoquinone (chloranilic acid) is adsorbed at the surface of a mercury drop electrode. The analyte ca
