Amperometric determination of zinc with an apoenzyme-treated graphite electrode

Zinc can be determined in the range 0.8–12 μM by activation of apo-alkaline phosphatase immobilized through covalent binding on a graphite electrode. o-Hydroxyphenylphosphate is used as substrate. Current is measured at an applied potential of 0.3 V vs. SCE.
