甲醛检测方法
Formaldehyde test method
1.甲醛污染问题主要集中于居室、纺织品和食品中。居室装饰材料和家具中的胶合板、纤维板、刨花板等人
1. Formaldehyde pollution is mainly concentrated in rooms, textiles and food. Plywood, fibreboard, particleboard, etc. in decorative materials and furniture
造板材中含有大量以甲醛为主的脲醛树脂,各类油漆、涂料中都含有甲醛。
There is a large amount of urea formaldehyde resin mainly used for making board, and formaldehyde is contained in all kinds of paints and coatings.
2.纺织品在生产加工过程中使用含甲醛的N-羟甲基化合物作为树脂整理剂,以增加织物的弹性,改善折皱性,还使用含甲醛的阳离子树脂以提高染色牢度。
2. In the production and processing of textiles, N-hydroxymethyl compounds containing formaldehyde are used as resin finishing agent to increase the elasticity and crease of fabrics, and cation resins containing formaldehyde are also used to improve the dyeing fastness.
3.造成纺织品中甲醛残留问题.另外,因经济利益驱使,一些不法分子以甲醛为食品添加剂,如水发食品加甲醛以凝固蛋白防腐、改善外观、增加 口感,酒类饮料中加入甲醛防止浑浊、增加透明度,这些都会造成食品的严重污染,损害人体健康。《中华人民共和国食品卫生法》中已明文规定禁止甲醛作为食品添加剂。由此可见,甲醛污染问题已普及到生活中的每一个角落,严重威胁人体健康,应引起人们的高度关注。甲醛含量已成为当今居室、纺织品、食品中污染监测的一项重要安全指标。因此研究一种市民可以在自己家中独立完成的,简便、灵敏、快速、直观、准确、经济的甲醛检测方法将会有很大的市场前景。
3. The problem of formaldehyde residue in textiles is caused. In addition, driven by economic interests, some lawbreakers use formaldehyde as food additives, such as adding formaldehyde to water-based food to coagulate protein to prevent corrosion, improve appearance and taste, adding formaldehyde to alcoholic beverages to prevent turbidity and increase transparency, which will cause serious food pollution and damage human health. The food hygiene law of the people's Republic of China has expressly stipulated that formaldehyde is prohibited as a food additive. It can be seen that formaldehyde pollution has been widely used in every corner of life, which seriously threatens human health and should be paid close attention to. Formaldehyde content has become an important safety index of pollution monitoring in living room, textile and food. Therefore, the research on a simple, sensitive, rapid, intuitive, accurate and economic formaldehyde detection method which can be independently completed by citizens in their own homes will have a great market prospect.
国内外居室、纺织品、食品中甲醛检测方法主要有:分光光度法、电化学检测法、气相色谱法、液相色谱法、传感器法等。
At home and abroad, formaldehyde detection methods in living room, textile and food mainly include: spectrophotometry, electrochemical detection, gas chromatography, liquid chromatography, sensor method, etc.
