摘要
用紫外可见分光光度计(UV-vis)测试了聚乙烯醇(PVA)水溶液和盐溶液的透明度,研究了PVA醇解度、电解质和温度对PVA溶液透明度的影响。实验结果表明,UV-Vis法是一种简便可行的测定PVA溶液透明度的方法。
The transmittance of poly ( vinyl alcohol) (PVA) aqueous solution and salt solution were characterized by UV-vis spectrophotometer. The effects of alcoholysis degree of PVA, electrolyte and temperature on the transmittance of PVA solution were investigated. The experimental results showed that UV-Vis method was a simple and feasible method to determine the transmittance of PVA solution.
