摘要
用高效液相色谱法测定了改性沥青中橡胶的含量。柱温30℃,检测波长222 nm,流动相为同等比例的正己烷、四氢呋喃和乙腈的混合液,UV检测器。该方法的相对标准偏差RSD≤1.5%,线性方程:y=800.94x+579.03,线性相关系数r=0.999 8。
A sensitive method was used to measure the content of styrene-butadiene rubber（SBR） in modified asphalt by HPLC. The temperature was set at 30℃ and a wavelength of 222 nm was used for the detector. A mobile phase of hexane, acetonitrile and THF with equal proportion was used. The RSD of this method is 1.5%, and a linear equation of y = 800. 94x ＋ 579. 03 with a correlation coefficient of r = 0. 9998 was obtained.
