• 介紹： 易溶于大多數(shù)有機(jī)溶劑，不溶于水。2-羥基-4-甲氧基二苯甲酮（二苯甲酮-3）是防曬化妝品中常用的紫外濾光片。它保護(hù)皮膚免受太陽的有害影響。本文報道了固相微萃取 (SPME)-氣相色譜-火焰離子化-質(zhì)譜法測定水中防曬成分及其痕量分析。;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.
