摘要
Abstract
The ultrfiltration membrane interception effect for different molecular weight PEG was determined using spectrophotometer.The maximum absorption band of different molecular weights PEG were researched by ultraviolet spectrophotometry.The influence of some factors on the polyethylene glycol solution absorbance,such as the amount of reagent,the color time were investigated.The optimum test conditions were that the content of iodine dosage was 1.0 mL,the content of barium chloride dosage 1.2 mL and color time control was 10 minutes.This method had simple operation,good stability,high accuracy and easy application.关键词
