摘要：

A determination method for formaldehyde based on micro-fluidic chip was developed in this study. Formaldehyde samples with 3-methyl-2-benzothiazolinone hydrazone hydrochloride (MBTH) and ammonium ferric sulfate were well mixed and reacted in a micro-fluidic chip, and signals in effluent were determined online. The correlation coefficient of calibration line was greater than 0.999, which indicated that signals of this device were highly positively correlated with formaldehyde concentration. The relative standard deviations (RSD) of same sample were less than 2% at different formaldehyde concentration levels, indicating perfect reproducibility of this method. Noteworthy, this method was affected significantly by temperature since the online signal was depended on the extent of reaction.
