摘　　要：通过双光束紫外可见分光光度计和傅里叶变换红外光谱仪测量了含阴离子聚丙烯酰胺溶液透射光谱,实验研究了其在波段190~900 nm和400~4000 cm^(-1)的光谱特性。研究表明:含阴离子聚丙烯酰胺溶液在196~260 nm紫外波段处存在较强吸收特性,而其在红外波段1881,2623 cm^(-1)处透光特性较好。阴离子种类不同对聚丙烯酰胺溶液光谱特性的影响规律不同,其中Cl^-、OH^-对聚丙烯酰胺溶液光谱透射特性影响很弱,而SO_4^(2-)、HCO_3^-、NO_3^-、CO_3^(2-)对聚丙烯酰胺溶液光谱透射特性存在一定的影响。The transmission spectra of the polyacrylamide solution containing anionic were measured by TU-1901/1900 double beam UV visible spectrophotometer and RPrestige-21 infrared spectrometer.The spectral characteristics in the wavelength band 190-900 nm and 400-4 000 cm-（-1） were experimentally studied.The results show that there is a strong absorption characteristic in the 196-260 nm of the anionic polyacrylamide solution,and the transmittance performance of 1881 cm-（-1） and 2 623 cm-（-1）in the infrared band is better.Different kinds of anions on the spectral properties of polyacrylamide solution are different,and the effect of Cl-- and OH--on HPAM solution spectral transmittance is very weak,and effect of SO4-（2-）,HCO3--,NO3--,CO3-（2-） on the transmission performance of the polyacrylamide solution spectra exist certain influence.
