Trace Cu(Ⅱ) can catalyze the oxidation and self-polymeric reaction of o-methoxyphnol in H3BO3-NaOH buffer. The optimum conditions kinetic parameters and reaction mechanism were investigated. Based on the reaction,the catalytic kinetic spectrophotometric method for determination of trace Cu(Ⅱ) was proposed. The linear range is 0～180 ng/25 mL with detection limit of 4.9×10-11g/mL. This method was used to determine copper in offscum of plumbean-zinc mine with satisfactory results.
