【摘要】 对分光光度法测定纸浆硬度(KMnO4值)进行了实验探讨,同时与传统的滴定法进行了分析比较,测定结果通过回归方程分析,确定出不同制浆方法、不同种类浆料分光光度法和滴定法测定值间的相关性;得出分光光度法测定纸浆的硬度(KMnO4值)不仅快速、简便,而且测定结果准确、可靠,对实际生产具有现实的指导作用。更多还原

【Abstract】 Comparing with the traditional titrimetric method, a new method of determinating pulp KMnO4 value using spectrophotometer was discussed. And the correlative coefficient of the two methods was studied using linear regression equation. The results showed that the method of spectrophotometer for determinating KMnO4 value is faster, more simple and reliable than the titrimetric method.更多还原
