摘要：

alpha-Cobalt (II) hydroxide (alpha-Co-SO4) was synthesized. Characterized by powder X-ray diffraction, FT-IR spectroscopy, as well as elemental analysis indicates the formation of alpha-cobalt (II) hydroxide. The synthesized alpha-Co (II) hydroxide was used to fabricate modified carbon paste electrode for the determination of dopamine. The alpha-Co-SO4/SDS/CPE was characterized by electrochemical methods and modified electrode was used to determinate dopamine (DA) and ascorbic acid (AA) simultaneously. The detection limit and quantification limits for DA were found to be 2.5 x 10(-7) mol/L and 5.3 x 10(-7) mol/L respectively. (C) 2012 Elsevier B.V. All rights reserved.
