利用 PVA 在硼酸介质中与碘生成蓝绿色络合物的特性，完善了一套规范的用分光光度法测定 PVA 含量的分析方法，可使废水中 PVA 测量范围增大至4g/L 。结果证明，PVA 在波长680 nm 处有最大吸收；测量时显色剂加入6mL（1mL I2-KI 和5mL H3 BO3）时测定效果较好；通过测定其吸光度，对比标准曲线，从而可计算出 PVA 的含量。

A suit of analysis method which could determine the content of PVA by spectrophotometry were completed . The determination range of PVA in wastewater was increased to 4g/L . The result showed that the maximum absorption wavelength of PVA was 680nm .The effect of the determination was best when 6mL of chromogenic reagent (1mL I2-KI and 5mL H3 BO3 ) was added .The content of PVA could be calculated through the determination of its absorbency and comparing standard curve .
