摘要  研究设计了一种由实验光路、轴向磁场发生装置、检测计算部分组成的,可同步测量旋光与磁致旋光效应的实验装置。利用该装置验证了葡萄糖溶液旋光角与浓度的线性关系,以及葡萄糖溶液、氯化钠溶液的磁致旋光角与浓度和磁感应强度的线性关系,并证实其维尔德系数随浓度呈线性变化。在 20 ℃温度下,测得葡萄糖溶液在 632.8 nm 和 465 nm 波长中的旋光率分别为 48.40±0.41 和 90.23±0.78,相对误差约为 3%; 葡萄糖溶液及饱和氯化钠溶液的维尔德系数与参考值相对误差为 3.1%和4.88%,精度可达到 10 mT( 100 Gs) 。本实验装置结构简单、现象可视化强、适用场景广泛,而且测量精度高、抗外界干扰能力强,对于大学物理实验中溶液浓度测量、手性物质检测等具有较好的实用性与使用前景。

Abstract:  This study presents an integrated experimental device composed of an experimental optical path,an
axial magnetic field generator,and a detection and calculation unit,which can realize the simultaneous
measurement of optical rotation and magneto-optical rotation effects.Using this device,the linear relationship
between the optical rotation angle of glucose solution and concentration is verified,as well as the linear
relationships between the magneto-optical rotation angles of glucose and sodium chloride solutions and
concentration and magnetic induction intensity.The linear variation of their Verdet constants with concentration
is also confirmed.At 20 ℃,the specific optical rotations of glucose solution at 632.8 nm and 465 nm are
measured to be 48.40±0.41 and 90.23±0.78,with a relative error of approximately 3%.The relative errors of
the Verdet constants of glucose solution and saturated sodium chloride solution compared with the reference
values are 3.1% and 4.88%,respectively,and the measurement accuracy can reach 10 mT( 100 Gs) .The
experimental device has a simple structure,clear experimental phenomena,wide applicability,high
measurement accuracy and strong anti-interference ability. It presents good practicability and application
prospects for solution concentration measurement,chiral substance detection and other experiments in college
physics teaching.
