二苯甲酮类紫外吸收剂的分析报告

3[min]2二苯甲酮类紫外线吸收剂Benzophenone Benzophenone-

-type Ultraviolet absorbers 二苯甲酮类紫外线吸收剂通常被添加到塑料中来抑制紫外线引起的老化。但是由于怀疑其有内分泌扰乱作用，如果排放到环境当中，担心会对生态环境造成影响。使用CAPCELL CORE C 18S2.7，对四种二苯甲酮类紫外线吸收剂进行分离。在梯度条件下，四种化合物在3min 内得到了良好分离。

Benzophenone-type ultraviolet absorbers are often added to plastic materials to protect them against ultraviolet deterioration.Being suspected endocrine disruptiors,their release into the environment is in a great concern for the biological system.Four benzophenone-type ultraviolet absorbers were efficiently separated within three minutes by the use of CAPCELL CORE C 18S2.7under gradient conditions.
