Voltammetric Study For Cuso4 in Presence of Safranin (Saf ) in Hcl Solutions using New Multicarbon Nanotubes Doped with Nano Tantalum Pentoxide Working Electrode
Journal Title: To Chemistry Journal - Year 2019, Vol 2, Issue 0
Abstract
Redox reaction for CuSO4 in the absence and presence of safranin (suffranine) was studied. We applied new electrode made from multicarbon nanotubes (MCNT) and nano (Ta2O5) in a mixture with 80% MCNT and 20% (Ta2O5) by weight. Two drops paraffin oil was added, drying till dryness in tip of copper electrode covered with heat shrink polymer to do good isolation. The electrode was purified and put in oven at 90°C till working in the morning. Scan rate effect was done for the redox reactions in absence and presence of safranin to explain the type of the used reactions in the study electrode chemically. The stablilty constants and Gibbs free energies of complexation resulting from the interaction of CuSO4 with safranin in 0.1 M HCl at 27.5°C were evaluated and discussing their resulting data.
