Abstract A new simple, sensitive and selective catalytic method for the determination of nanogram level of copper(II) is proposed. N,N-Di-methyl-p-phenylenediamine reacts with N,N-dimethylaniline to form Bindschedler’s Green leuco base (BGL) and in the presence of hydrogen peroxide, copper(II) catalyzes the oxidation of BGL to a colored compound (λmax=725 nm).
