Electrochemical Studies of Paraquat Adsorbed onto Crystalline Apatite
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2007, Vol 6, Issue 11
Abstract
The carbon paste electrode (CPE) has been used to analyze the electrochemical behavior of paraquat (PQ) adsorbed onto synthesized hydroxyapatite phosphocalcique (HAP) in K2SO4 (0.1M). The cyclic voltammetry results obtained corrobate with square wave voltammetry. The influence of variables such as the concentration of paraquat adsorbed onto apatite (PQ/HAP), and the potential scan rate was tested. X-ray diffraction analysis (XRD), Fourier transformed infrared spectroscopy (FTIR) analysis and inductively coupled plasma-atomic emission spectrometry (ICP, AES) were used for characterization of the apatite.
