Abstract: | At 1.5 V applied between the electrodes on the piezoelectric crystal, many metals electrodeposit on an electrode so that the frequency changes. Iron(III) (1 × 10?5-1 × 10?4 M) can be determined by adsorption of iron(III) phosphate which also causes a frequency change. Electrodeposition can be prevented by covering one electrode with a thin glass plate. |
