摘要
论述了在土壤中脲甲醛分解后可能产生的甲醛的提取和测定方法,经过比较,确定在今后分析中采用水蒸气蒸馏提取土壤中的甲醛,然后用乙酰丙酮分光光度法进行测定。
The extract and measuring methods of possible produced formaldehyde by urea formaldehyde in soil were discussed. According to the stated methods, water vapor distillation and acetylacetone spec- trophotometric method were selected to analyze the formaldehyde in soil in the near future.
