Study on Transmittance of PEO Aqueous Solution by Spectrophotometry

用分光光度法测试了不同相对分子质量不同浓度的聚氧化乙烯(PEO)水溶液及其三元溶液的透明度,对相对分子质量、浓度、电解质和温度对聚氧化乙烯溶液透明度的影响进行了探索.此方法简单有效、方便快捷、实验结果鲜明直观,为研究中低相对分子质量聚氧化乙烯(PEO)水溶液透明度开辟了一条新的途径.

The transmittance of PEO aqueous solution and salt solution were characterized by spectrophotometrer method.The effects of molecular weight of PEO,concentration electrolyte and temperature on the transmittance of PEO solution were investigated. The method is simple,effective and speedy,it proposed a new way to study PEO solution of middle-low molecular weight.
