【摘要】 建立测定水性涂料和胶粘剂中甲醛含量的乙酰丙酮分光光度法。测定甲醛的线性范围为0.00～80.29μg,相关系数为0.9999,水性涂料和胶粘剂样品中甲醛含量测定结果的相对标准偏差分别为3.2%、2.8%,回收率分别为89%～93%、90%～96%。更多还原

【Abstract】 The method for the determination of formaldehyde in water-base coating and adhesive by acetylacetone spectrophotometry was set up. The linear range of formaldehyde was 0.00~80.29 μg and the correlative coefficient was 0.9999. The method was applied to the determination of formaldehyde in water-base coating and adhesive, the relative standard deviations were 3.2% and 2.8%, the recoveries were 89%~93% and 90%~96% respectively.更多还原
