摘要
本文叙述了运用盐酸—硝酸—高氯酸组合对竹浆黑液样品进行处理,得到无色溶液,再运用1,10菲罗啉法测定竹浆黑液中铁含量,其平均回收率为98%,相关系数R=0.99948能够应用于竹浆黑液中铁含量的分析。
This article described the treatment of bamboo pulp black liquid by hydrochloride acid-nitric acid-perchloric acid,obtaining colorless solution.Then the iron content of bamboo pulp black liquid determined by ferroin（1,10-phenanthroline） methods,its average recovery rate was 98%,correlation coefficient R was 0.99948,so that the method can be used for analysis of iron content in bamboo pulp black liquid.
