摘要
在碱性条件下,甲醛与水合氧化银发生氧化还原反应,生成的银定量还原Fe(Ⅲ)为Fe(Ⅱ),Fe(Ⅱ)与磺基荧光酮在CTMAB存在下形成三元络合物.利用分光光度法测定该络合物以间接测量织物的甲醛含量,该法是测定织物中甲醛量的一种简便。
A method of determination of formaldehyde indirectly by spectrophotometry was described.Formaldeˉhyde reacted with hydrous silver oxide in alkaline medium and formed silver which could react with Fe(Ⅲ)and suˉfofluorone in CTMAB medium to form ternary complexes.This is a new method for determination of formaldehyde in the fabric.It is simple and accurate.
