茶叶提取物与甲醛的反应检测

甲醛是室内装修材料中重要的污染源．为了有效控制甲醛的释放，对茶叶有效成分进行提取，所得提取物配成除醛剂，可以用于去除甲醛．选择加液量、反应温度和反应时间为提取因素，采用正交实验方法得到最佳提取工艺，所得产品对甲醛去除率可以达到61．77％．为了能够充分提取茶叶有效成分，还对茶叶进行多次提取，发现多次提取物除醛效果明显下降．3次后提取物几乎不再有除醛效果．

Research on formaldehyde reaction with extracting substance from tea

Formaldehyde is the main pollution from the material of indoor fitment. To control the release of formaldehyde, the tea extracting substance, which is mixed to formaldehyde-cleaning agent, is acquired to remove it. Chosen the factors such as liquid quantity, reaction temperature, and reaction time, the orthogonal experiment method is used to find the optimization condition. The best removal efficiency will be made to 61.77%. The extraction is made time after time for acquiring the available component adequa...
