Isobutanol effect on the production rates of copper powder on rotating zinc disc

The rates of copper/zinc cementation reaction in isobutanol‐water mixture was measured at different temperatures using an atomic absorption spectrophotometer. The rate of cementation decreases with increasing the percentage composition of alcohol, and increases by increasing temperature and the rate of rotation. Thermodynamic parameters ΔH*, ΔG* and ΔS* were calculated.
