【摘要】 为提高海产品副产物的再利用,本文选用废弃牡蛎壳及甘氨酸为主要原料,采用水相合成法制备螯合物。以投入灰分与甘氨酸的质量比,加水量及反应时间为三个影响因素,在90～100℃水相条件下搅拌反应,通过单因素试验和正交试验分析,得出最适宜螯合条件,按主次顺序为:甘氨酸与灰分质量比为1:3,甘氨酸浓度2.5%,反应时间30min。更多还原

【Abstract】 To enhance the rate of reuse of seafood by-product,we choose discarded oyster shells and Glycine as the main raw material,using water-phase synthesis to prepare chelate.The mass ratio of ash and Glycine,add water and the reaction time are the three factors,The reaction under the conditions of aqueous phase in the 90～100℃,with stirred tank reactor.Through the single factor experiments and orthogonal test and analysis,finding the most suitable conditions for chelation,according to primary and secondary in the order:Glycine and ash ratio of 1:3,Glycine concentration of 2.5%,reaction time is 30min.更多还原
