Applications of enzyme-catalysed reactions in trace analysis--I. Determination of mercury and silver by their inhibition of invertase.
Procedures are described for the accurate determination of silver (2-10 x 10(-7)M) and mercury(II) (2-10 x 10(-7)M) in the presence of each other and of most other metals. The methods are based on the inhibition by these metals of invertase catalysis of the hydrolysis of sucrose.
