Poly(glutamic　acid)　(P-GLU)/carboxyl　functionalized　multiwalled　carbon　nanotubes　(MWCNTs-COOH)/polyvinyl　alcohol　(PVA)　modified　glassy　carbon　electrode　(GCE)　has　been　successfully　prepared　and　the　electrochemical　behavior　of　procaterol　hydrochloride　(ProH)　was　studied.　The　results　show　that　the　as　prepared　modified　electrode　exhibits　a　good　electrocatalytic　property　towards　the　oxidation　of　ProH　in　0.2　M　phosphate　buffer　solution　(PBS)　(pH　6.0)　due　to　the　enhanced　oxidation　peak　current　at　similar　to+0.59　V.　Under　optimal　reaction　conditions,　the　oxidation　peak　current　of　ProH　is　proportional　to　its　concentration　in　the　linear　dynamic　ranges　of　0.060　-　8.0　mu　M　(R　=　0.9974),　with　a　detection　limit　of　8.0　x　10(-9)M.　Finally,　this　method　was　efficiently　used　for　the　determination　of　ProH　in　tablets　and　human　urine　with　recoveries　of　88.5　similar　to　98.7%　and　89.2　similar　to　108.0%,　respectively.
