EXPERT-SYSTEM FOR THE VOLTAMMETRIC DETERMINATION OF TRACE-METALS .5. METHODS FOR DETERMINING TOTAL IRON, MANGANESE(II), ALUMINUM AND TITANIUM

A previously described expert system for the voltammetric determinatio n of Cu, Zn, Cd, Pb, In, Ni, Co, TI, Hg, V, Se, Te, Cr(III), Cr(V), As (III) and As(V) is enlarged and improved by including methods for the determination of total Fe, Mn(II), Al and Ti, Pulse polarographic and stripping voltammetric techniques are considered. Although in some cas es solid electrodes are mentioned, mercury drop electrodes are mostly recommended. The expert system is developed using the commercially ava ilable building tool KES.
