| Abstract: | Nanosized CuO powder was synthesized by solid-state coordinated and decompounded reaction, and characterized by X-ray diffraction and transimssion electron microscopy. The results showed that the average particle sizes of nanosized CuO are about 10 nm. A new chemiluminescence system, Nanosized CuO]-luminol-Amino acid], was proposed to determine the catalytic abilities of nanosized CuO. The catalytic abilities of nanosized CuO were enhanced by 5.65 and 4.51 folds than those of analytical CuO and copper sulfate, ~respectively . The detection limit of amino acid was 10~-9 mol/L. |
