Abstract:
Objective To study the catalytic capability of glucosamirie-Cu( Ⅱ) complex for decomposition of H2O2 and its relative factors. Methods Glucosamine-Cu( Ⅱ ) complex was prepared by the reaction of D-glucosamine hydrochloride with Cu2+ in aqueous solution, then added it into H2O2 solution. The concentration of H2O2 was determined by titrimetric analysis in a regular interval of time, the rate of decomposition of H2O2 was obtained in various conditions. Results Strong catalytic capability of glucosamine-Cu( Ⅱ ) complex was obtained at 30℃ pH 6. 5, the rate of decomposition was over 90% after 12h, and was almost 100% after 24h. Conclusion The complex of glucosamine-Cu( Ⅱ ) showed good catalytic capability for decomposition of H2O2.
