摘要
目前用于测定植酸的方法要么设备、标准品昂贵,要么消化困难,终点难以判断,不适于一般的常规分析。经过分析比较,发现硝酸钍返滴定法、铜盐-碘量法、三氯化铁滴定法可快速、准确、简便地测定植酸含量,适用于一般的工业分析和科研。
At present Determinations of phytic acid that is either equipment,standard high or digestive difficulties,the end is hard to determine are not suitable for routine analysis of general.After analysis and comparison,we found that Titrimetric analysis of phytate by back titration with thorium、copper-Iodometry and Iron trichloride iron titrimetric method can fast,accurately,simple determine the phytic acid content,they are suitable in the general technical analysis and the scientific research.
