• 介绍： 易溶于大多数有机溶剂，不溶于水。2-羟基-4-甲氧基二苯甲酮（二苯甲酮-3）是防晒化妆品中常用的紫外滤光片。它保护皮肤免受太阳的有害影响。本文报道了固相微萃取 (SPME)-气相色谱-火焰离子化-质谱法测定水中防晒成分及其痕量分析。;2-Hydroxy-4-methoxybenzophenone (benzophenone-3) is commonly employed as broad-band UV-filter in sunscreen cosmetic products. It protects skin from the deleterious effects of the sun. It is one of the sunscreen constituent and its trace determination in water samples by solid-phase microextraction (SPME) and gas chromatography with flame ionization and mass spectrometric detection has been reported.
