Abstract: Anodic amperometry of nine C3 and C4 alcohols and diols, plus ethanediol and glycerol, was studied at +0.55 V (vs. the SCE) in 0.1 M NaOH containing suspended Ni(OH)2 (from adding 10 mM NiSO4). The flow injection cell contained a 10-mm Ni-wire (0.64 mm diameter) working electrode and a 20-mm Pt-wire auxiliary electrode. The upper limit of rectilinearity (peak current vs. concentration.) was ~0.25 mM and the lower detection limit was 0.2 µM (propane-1,3-diol). Primary alcohols yielded larger current sensitivities than secondary alcohols.
