摘    要:低场磁共振技术是一种新型无损检测方法,具有快速、准确和环保的优点。微孔淀粉是一种新型的变性淀粉,其表面具有均匀无数的孔洞,具有很好的吸附特性,可以吸附油脂、色素等物质。本实验利用低场磁共振法具有测试的时间短、不需要溶剂、操作简便、准确及可靠性高等优点,首次测定了微孔淀粉的吸附特性,为未来微孔淀粉的吸附特性研究提供了一种高效、先进的方法。

关 键 词:低场磁共振技术  无损检测  微孔淀粉  吸附率  油脂

Abstract:Low field nuclear magnetic resonance(NMR) technology,a new nondestructive testing method,has advantages such as rapid,accurate and pollution-free.Microporous starch is a new type of modified starch,its surface has a uniform countless holes,has the very good adsorption characteristics.It can absorb grease,pigment and other substances.Low field nuclear magnetic resonance method can test in a short time and need not solvent.Its operation is simple,accurate and high reliability.The first determination of the microporous starch adsorption properties provides a kind of high efficient and advanced methods for the future research of adsorption properties of the microporous starch.
Keywords:Low field nuclear magnetic resonance  Nondestructive testing technology  Microporous starch  Absorption rate  Oil
