摘要
本文研究了近红外仪在近红外区域(1100- 2500nm ),多重线性回归测定二醋酸纤维素的醋化值的方法。并且就近红外仪测试二醋酸纤维素醋化值的测试结果与传统滴定结果进行了比较,对测量的重现性进行了考察,相对标准偏差为0.07% 。
A near infrared spectrometer (NIR) was used to determine acetyl value of cellulose diacetate(CA) in near infrared spectral region(1100-2500nm) with multiple linear regression(MLR). The result was compared with that by traditional titration. The reproducibility was investigated ,and the relative standard deviation of the method was 0.07%.
