Inhibition behavior of acid phosphatase, phosphodiesterase I and adenosine deaminase as tools for trace metal analysis and speciation

Simple inhibition tests are described for acid phosphatase, phosphodiesterase I and adenosine deaminase. From 23 different metals tested, the following ions affect the enzymes' activity (detection limits in 0.5 ml synthetic solution): inhibition of acid phosphatase: Hg 2+ (0.1 mg/l) and Cu 2 +...
