Electrochemical investigation of oxytrol in fizzy drinks and juices via graphene and polymer printed PVC by ANOVA and design expert

Electrochemical behavior of sensors

Calibration was done by submerging the electrode in oxytrol solutions with a double junction Ag/AgCl reference electrode across a concentration range of 1.0 × 10^–9–1.0 × 10^–2 mol L⁻¹ to…
