In　the　present　study,　procaterol　hydrochloride　(ProH)　was　successfully　electropolymerized　onto　a　glass　carbon　electrode　(GCE)　with　simply　cyclic　voltammetry　scans　to　construct　a　poly(procaterol　hydrochloride)　(p-ProH)　membrane　modified　electrode.　Compared　with　the　bare　GCE,　much　higher　oxidation　peak　current　responses　and　better　peak　potentials　separation　could　be　obtained　for　the　simultaneous　oxidation　of　dopamine　(DA)　and　uric　acid　(UA),　owning　to　the　excellent　electrocatalytic　ability　of　the　p-ProH　membrane.　And　it＇s　based　on　that　a　square　wave　voltammetry　(SWV)　method　was　developed　to　selective　and　simultaneous　measurement　of　DA　and　UA.　Under　the　optimum　conditions,　the　linear　dependence　of　oxidation　peak　current　on　analyte　concentrations　were　found　to　be　1.0-100　mu　mol/L　and　2-100　mu　mol/L,　giving　detection　limits　of　0.3　mu　mol/L　and　0.5　mu　mol/L　for　DA　and　UA,　separately.　The　as　prepared　modified　electrode　shows　simplicity　in　construction　with　the　merits　of　good　reproducibility,　high　stability,　passable　selectivity　and　nice　sensitivity.　Finally,　the　proposed　p-ProH　membrane　modified　electrode　was　successfully　devoted　to　the　detection　of　DA　and　UA　in　biological　fluids　such　as　human　serum　and　urine　with　acceptable　results.
