食品中铜的测定方法有二己脸基二流代甲酸钠比色法和原子吸收分光光度法[1]，前法灵敏度较低且要用有毒的四氯化碳革取，后法需用昂贵的仪器。我们参考文献［2］合成了3－丙基－5－羟基－5－四羟了基－3－噻唑烷基疏附－2（PHTTT），拟定了测定食品中微量钢的新方法。实验表明 Determination of copper in food has two hexamers face two sodium formate colorimetry and atomic absorption spectrophotometry [1], the former method is less sensitive and toxic carbon tetrachloride leather, the latter method requires expensive instrument. We synthesized the 3-propyl-5-hydroxy-5-tetrahydroxyl-3-thiazolidinyl-2-phosphate (PHTTT) and developed a new method for the determination of microalloyed steel in food [2]. Experiments show
