报道了杨梅红色素的提取与性质。基于加热条件下 ,Zn2 + 催化过氧化氢氧化杨梅红色素灵敏的褪色反应 ,提出了测定痕量锌的新方法。所建立的方法对Zn2 + 的线性范围为 0 .2～ 1 .0 μg L,并成功地用于发样和奶粉中锌的测定
Reported the extraction and properties of bayberry red pigment. A new method for the determination of trace zinc was proposed based on the sensible decolorization reaction of bayberry red pigment catalyzed by hydrogen peroxide catalyzed by Zn2 +. The established method for Zn2 + linear range of 0.2 ~ 1.0 g L, and was successfully used in hair samples and milk powder determination of zinc
