Recebido em 14/2/13; aceito em 9/5/13; publicado na web em 17/7/13In this study, the adsorption isotherm of copper (II) on a calcium phosphate host intercalated with 4-aminobenzoic acid in an ethanol solution was investigated. This gave a maximum adsorption capacity of 1.74 mmol g -1 . The material was incorporated into a carbonpaste electrode, and its electrochemical properties were investigated. However, for a dopamine solution, the anodic peak current increased owing to the electrocatalytic oxidation. The electrode presented the same response for at least 150 successive measurements, showing good repeatability. The modified electrode is very stable and reproducible. The electrode sensor was successfully applied for dopamine determination in pharmaceutical preparations.
The following article has been retracted due to the investigation of complaints received against it. The Editorial Board found that substantial portions of the text came from other published papers. Unethical behavior such as self-plagiarism and misuse of published figures and data without copyright consent will be treated very seriously. The scientific community takes a very strong view on this matter, and the OJSTA treats all unethical behavior such as plagiarism seriously.
