14.9.1.2 Iodide and iodate
Cathodic stripping square wave voltammetry has been used to monitor vertical profiles of
iodide, iodate and free iodine in non saline waters periodically during the course of a year
[57].
14.10 Polarography
14.1 0.1 Non saline waters
14.10.1.1 Iodide and iodate
Differential pulse polarography has been used [57] to monitor vertical profiles of iodide,
iodate and free iodine in non saline waters periodically during the course of a year.
14.10.2 Potable waters
14.10.2.1 Nitrate, perchlorate and iodide
Marecek et al. [58] investigated the feasibility of using a hanging drop electrode for the
determination of nitrate, perchlorate and iodide in potable water. A three-electrode
system was used with a polarographic analyser. The potential range of the method was
increased by using crystal violet dicarbollylcobalate electrolyte in the nitrobenzene phase
and magnesium sulphate in the aqueous phase, with a lead/lead sulphate reference
electrode.
14.11 Ion selective electrodes
14.1 1.1 Mineral waters
14.11.1.1 Sulphide and cyanide
Jovanovic and Jovanovic [59] have described a method for the determination of sulphide
and cyanide in spa water using a deposited on wire silver-silver sulphide ion selective
electrode.
14.11.2 Waste waters
14.11.2.1 Thiosulphate, sulphide, sulphite, sulphate and polysulphide
Sulphide, thiosulphate, sulphite, sulphate and polysulphide have been determined in
