| Study on Chelate of Complex Amino Acid with Copper |

| Abstract: |
| Complex amino acid prepared from hydrolyzate of waste chicken feather by sulfuric acid was chelated with CuSO 4·5H 2O. The highly pure chelate of complex amino acid with copper was then deposited by the addition of organic solvent and analyzed by chemical method and IR spectra. A new procedure for determing chelation ratio, which based on the direct determination of microelement in the chelate, was also reported. |
