Abstract
A procedure of chelatometric determination of cobalt, nickel and lanthanoids based on back titration with Cu(II) ions using copper ion selective electrode has been developed and applied to alloys for novel type permanent magnets. In addition, a method has been worked out for direct titrimetric determination of lanthanoids with solution of fluoride ions in 75% ethanol using fluoride ion selective electrode.
