摘　　要：选择水体系合成法制备理化性质稳定的蛋氨酸螯合铜,用化学分析和仪器分析进行表征。以蛋氨酸和氯化铜按物质的量比为2︰1投料,水溶后以氨水调节p H值至5,恒温80℃,回流反应4 h,结晶,洗涤,烘干。以EDTA滴定分析铜含量,凯氏定氮法分析氮含量,确定化学式为Cu(Met)2,结合红外光谱分析,确定了蛋氨酸螯合铜的结构。The paper studies the make of stable methionine copper using water system synthesis method and represents the make through chemistry and instrument analysis. The quality ration of methionine and copper chloride is 2 to 1, p H value is kept to 5 using ammonia water, temperature is kept to 80℃, reflux time is kept to 4 hours while crystallization, washing and drying. Copper quality is measured by EDTA titration, nitrogen quality is measured by Kjeldahl method, Cu（Met）2 is verified by infrared spectroscopic analysis.
