A new sensitive catalytic method for the determination of copper(II) is proposed.In the presence of hydrogen peroxide, copper(II) catalyzes the oxidation of p-hydrazinobenzenesulfonic acid to p-sulfobenzenediazonium ion, which is coupled with m-phenylenediamine to form a yellow azo dye (λmax = 454 nm).By means of this catalytic reaction, nanogram amounts of copper(II) can be determined easily.
