摘要
为了对甲醛的浓度进行快速、准确的测定,研究了甲醛的激光拉曼光谱激发机理,并对采集的标本进行了检测,并对结果进行了分析和论证。该方法不需辅助试剂,直接测量甲醛分子振动产生的拉曼光谱,根据甲醛特征谱的峰值,确定甲醛的浓度。得到一种低成本、快捷的甲醛浓度检测方法。
Based on the study on the formaldehyde laser - Raman spectrum stimulation mechanism, a kind of low cost method of rapid and accurate determination on the concentration of formaldehyde can be got by the means of examining gathered specimen followed with analysis and proof to the result. This method, without any assistant reagent, is to survey directly the Raman spectrum which the vibration of formaldehyde molecular produces, and then to definite formaldehyde density according to formaldehyde characteristic spectrum peak.
