用废弃蛋白质制备混合氨基酸稀土配合物的研究

STUDY ON THE SYNTHESIS OF THE RARE EARTH AMINO-ACIDS COMPLEXES BY THE WASTE PROTEIN

用鸡羽毛、猪血粉、头发、豆饼等经酸解工艺制混合氨基酸，进而与混合稀土合成稀土氨基酸配合物。对水解工艺和合成工艺的条件作了研究，并对配合物的稀土含量、总氮量和各种氨基酸含量作了较全面的化学分析。

Abstract The mixed amino-acids were prepared byacidic hydrolysis technology from the chickenfeather,the pig-blood,the hair and the beanresidue. The complexes were synthesized fromthe mixed amino-acids and the rare earth chlo-ride. In this paper,the conditions for hydroly-sis technology and synthesis technology werestudied,meanwhile the rare earth content,thetotal nitrogen content and the amino-acidscontent in the complexes were determined too.
