| 摘 要：建立了检测PVB产品水洗质量的方法。通过比较研究,选择以Cl-1为标识物,水为溶剂,用硫氰酸汞分光光度法检测PVB产品水洗质量。氯离子含量在20～100μg/10mL范围内与其吸光度呈正线性相关,检出限为8.4μg/10mL。回归方程为A=0.0024X(μg/10mL)-0.003,相关系数r2=0.9986。该方法准确、可靠、简便、实用。 |

| Abstract：A method for testing the washing quality of product polyvinylbutyral was established.Water was used to be solvent,and mercury thiocyanate absorptiophotometry was selected to determine the content of chlorine ion in the products.Positive linear relationship was found between the absorbance value and the content of chlorine ion in the range of 20～100 μg/10 mL.The detection limit is 8.4 μg/10 mL.The Regression equation was as follow:A = 0.0024X(μg/10 mL)-0.003,the correlation coefficient r2=0.9986,indicatng th... |
