A potentiometric titration for H2O2determination in the
presence of organic compounds
M.P.Gimeno,* M.C.Mayoral and J.M.Andres´
A new method for the quantitative analysis of hydrogen peroxide in the presence of organic substances is
described and discussed.The method is based on the potentiometric titration of hydrogen peroxide with
sodium hydrogen sulphite and has been successfully applied to the detection and quantification of the
remaining peroxide content in the oxidation of glycerol by H2O2.This method has been tested:the
linear range covered was between 17.750 and 0.079 mM.The standard deviation for the low range
studied (0.234–0.079 mM) was 0.001 mM,and the limit of quantification (LOQ) obtained for the
proposed method was 0.02 mM.The acidity of the peroxide solution showed no influence on the
developed method and was sufficient to prevent H2O2 decomposition,while neutral or alkaline pH
caused partial decomposition of H2O2.The metrology,including accuracy,precision or relative error and
reproducibility of the measurements,is discussed.

在有机化合物存在的情况下,测定过氧化氢的电位滴定
M. P. Gimeno,* M. C. Mayoral 和 J. M. Andres´
本文描述和讨论了在有机化合物存在的情况下,一种用于定量分析过氧化氢的新方法.该方法基于在氢钠亚硫酸盐存在时,过氧化氢的电位滴定.该方法已成功应用于过氧化氢氧化甘油的过程中,剩余过氧化物含量的检测和量化.该方法已经过检测：被覆盖的线性范围在17.750至0.079毫米之间.研究表明低范围(0.234 -0.079毫米)的标准偏差是0.001毫米,且该方法的最低检测限是0.02毫米.酸性过氧化氢溶液显示其对改良后的方法没有影响,且足以防止过氧化氢的分解,然而中性或碱性条件下会造成过氧化氢的部分分解.本文同时对计量的准确度、精确度、相对误差、测量值的可再现性进行了探讨.
