研究了铁-邻二氮杂菲间接分光光度法测定甲醛的反应条件,建立了甲醛的测定方法,探讨了织物防皱整理中所用树脂原料对甲醛测定的影响。用本法测定织物中游离甲醛,结果满意。
The reaction conditions for the determination of formaldehyde by iron-phenanthroline indirect spectrophotometry were studied. The determination method of formaldehyde was established and the influence of the resin raw materials used in crease-proof finishing on the determination of formaldehyde was discussed. Using this method to determine free formaldehyde in fabrics, the results are satisfactory.
