本文初步探讨了磁性物质Fe3O4和海藻酸钙形成凝胶小球的操作条件和影响因素。实验表明,采用海藻酸钠溶液滴入氯化钙溶液的加料方式,可形成质地均匀的磁性海藻酸钙凝胶小球;海藻酸钠溶液的浓度是影响磁性凝胶小球包载量、包封率和含水率的主要因素,其适宜的浓度范围分别为2%(w/w)~4%(w/w)。 In this paper, the operating conditions and influencing factors of gelatin pellets formed by magnetic materials Fe3O4 and calcium alginate were preliminary discussed. Experiments show that the use of sodium alginate solution dropping calcium chloride solution can form a uniform texture of magnetic calcium alginate gel beads; sodium alginate solution concentration is the impact of magnetic gel beads package, including the package The suitable concentration ranges of 2% (w / w) ~ 4% (w / w), respectively, are the main factors for the recovery rate and moisture content.
