Organoclay-film modified electrode for the detection of ultra-traces of Hg2+ ions: Approach of one factor at a time by an experimental design

Autor: Liliane M. Dongmo, Ervice Ymele, Ignas Kenfack Tonle, Sherman L.Z. Jiokeng, Divine B. Nde

Publikováno v: Electrochimica Acta. 316:152-161

Ultra-trace levels of Hg2+ were detected by DPASV at a glassy carbon electrode modified by an amino-functionalized attapulgite as bulk material, in aqueous solutions containing Hg2+ alone and with Cd2+ and Pb2+. XRD, SEM and TGA/DTG analysis were use
