| 摘 要： | 光度法测定甲醛,灵敏度高、选择性好、成本较低,但对化妆品样品的前处理时间较长.目前用光度法快速测定化妆品中甲醛的方法尚未见报道.用乙酰丙酮作显色剂,提高反应速率,以50％异丙醇作测定溶液,即能解决样品前处理时间长的缺陷.甲醛的方法检测限为0.78 mg/L.回收率范围95％～97％,RSD为0.5186％～2.0032...

| Abstract: | Determination of formaldehyde by spectrophotometer is a method with high sensitivity,good selectivity and low cost,but the pre-treatment of samples for cosmetics is longer.Rapid Determination of formaldehyde in cosmetics by this method has not been reported so far.The method here is as follows: using acetyl acetone reagent to accelerate the reaction rate,50% isopropyl alcohol solution was used as detection solution,which can solve the longer sample preparation times problem.The detection limit for formaldeh... |
