摘　　要：提出了光学检测聚丙烯酰胺溶液的方法,利用TU-1901/1900双光束紫外可见分光光度计、IRPrestige-21傅立叶变换红外光谱仪测量5~600mg·L-1浓度范围内聚丙烯酰胺溶液的透射光谱,研究了其在波段190~900nm和400~4 000cm^(-1)的光谱特性,进行了其浓度的反演分析。研究表明:聚丙烯酰胺溶液在200~300nm和400~920cm^(-1),2 986~3 684cm^(-1)范围存在较强吸收特性,其透光度在220nm,2 623cm^(-1)处有一定的线性关系;在紫外波段基于2,3和4个透光度测量值反演其未知浓度的计算误差最大值分别为6.98%,2.34%和0.79%。The method of optical detection to test polyacrylamide solution was developed which took advantage of TU-1901/1900double-beam UV-Vis spectrophotometer and IRPrestige-21FT-IR Spectrometer to measure the transmitted spectrum of polyacrylamide solution in the range of 5600mg·L-1 concentration.The spectrum characteristics and inverse analysis their concentrations of polyacrylamide solution within the wavelength of 190900nm and 4004 000cm-1 were investigated.The results show that there are strong absorption of polyacrylamide solution in 200300nm,400920cm-1,29863 684cm-1 and the transmittances of solution with different concentrations have linear relationship at 220 nm and 2 623cm-1;the maximum calculation error to inverse the unknown concentrations successively are 6.98%,2.34%and 0.79%,when inversion calculation uses 2,3,4measured values in ultraviolet band.
