Metomega Chrome Blue BBL was used as a metal indicator for the detection and titration of calcium, magnesium, manganese, nickel and manganese. A displacement reaction was described for the titration of cadmium using Mn-EDTA. A stepwise titration was conducted for the direct titration of both calcium and magnesium in blood serum.
Fenugreek mucilage was used as a media for increasing the sensitivity limits of detection of barium, cadmium, cerous, calcium, copper, cobalt, magnesium, manganese, nickel, lead and zinc.
