摘要
本文应用国产JS-1A激光小角光散射仪,以1 mol/L NaNO3作溶剂,对水体系聚丙烯酰胺的分子量进行了研究测定,并与粘度法进行了比较。结果表明,该法对测定高聚物分子量方法可靠,平行稳定性好,精密度高,测定结果符合误差允许的范围要求。
Using JS-1A laser scatter, taking 1 mol/L NaNO3 as solvent, the molecular weight of polyacrylamide in water system was measured, and this method was compared with viscosity method. The results expressed that this method was reliable, stable and accurate when was used to measure molecular weight of high polymers.
