摘要
目前测定过氧化值的方法主要有GB/T5538-2005和GB/T5009.37-2003两种方法,而在过氧化值较大时,GB/T5538-2005方法过氧化值测定值显著大于GB/T5009.37-2003方法测定值。文章通过GB/T5009.37-2003的方法做对比,对GB/T5538-2005方法进行优化。结果表明试验方案2切实可行,测得过氧化值准确,不会显著偏高。
At present the method of determination for peroxide value, mainly include GB/T5538-2005 and GB/T5009.37-2003. Method GB/T5538-2005 determination of peroxide value significantly greater than the method of GB/T5009.37-2003 when the peroxide value in high leve. The paper means to optimize the method of GB/T5538-2005 by comparing to GB/T5009.37-2003. The results show that test 2 is feasible and Peroxide value can be measured accurately, not significant on the high side.
