摘要
采用激光拉曼光谱对不同生产阶段自来水样品的硬度指标进行了研究,测量了水样品拉曼谱的弯曲振动峰与伸缩振动峰强度的比值,并计算了样品在伸缩振动拉曼峰处的退偏振度。结果表明,随着水样品总硬度的减少,弯曲振动峰与伸缩振动峰强度的比值和样品在伸缩振动拉曼峰处的退偏振度均随之减少。
Abstract
Laser Raman spectrum method was used to study hardness index of tap water sample in different stages of waterworks production. Ratio between the bending vibration peak intensity and stretching vibration peak intensity of water samples was measured. Depolarization ratio of laser Raman spectrum at stretching vibration was also calculated. The results show that ratio between the bending vibration intensity and stretching vibration intensity of water samples decreases with the decrease of the samples’ total hardness, and depolarization ratio of laser Raman spectrum at stretching vibration decreases too.
