摘要
在酸性介质中,基于甲醛对溴酸钾氧化铬蓝黑R有显著的促进作用,建立了测定微量甲醛的动力学催化光度法。用该方法对某织物和某实验室废水中甲醛含量进行了测定,并与乙酰丙酮法比较,结果满意。
A simple and sensitive kinetic catalytic spetrophotometic method is reported for the determination of trace amount of formaldehyde based on the catalytic effect of formaldehyde on the oxidation of Erichrome black R （EBR）with potassium bromate in sulfuric acid media. This paper uses the method to determined trace formaldehyde in textile and in wastewater. The results thus obtained show good agreement with those determined by acetyl acetone method.
