| 摘 要： | 探讨酸菜在铜质容器中熬煮,砷、汞、铅、镉、铬、镍、铜等元素含量的变化.以微波消解预处理样品,运用ICP-MS、HG-AFS法测定铜锅熬煮酸菜过程中汤料、酸菜中重金属元素的含量变化.在紫铜锅中熬煮酸菜6 h,可使锅体汞、铅、铜溶出较多,镉、铬、镍少量溶出,基本无砷溶出.其中,汤料中汞、铅、铜、镉、铬和镍分别约增加914%、65%、513倍、55%、46%和60%,酸菜中汞、铅、铜、镉、铬和镍分别增加81%、159%、375倍、19%、142%和70%.从健康角度出发,紫铜锅可能不适宜作酸菜类火锅的烹饪容器.

| Abstract: | This paper investigates the changes of the contents of some heavy elements ions such as As,Hg,Pb,Cd,Cr,Ni,Cu in pickles during cooking in copper pots.HG-AFS and ICP-MS were used to determine the contents of these heavy metals in pickles samples and their soups after they were digested with microwave digestion system.Much Hg,Pb,Cu and a little Cd,Cr,Ni and little As were liberated from the pot body when the copper pot was used for cooking pickles after 6 huors.Compared to the contents of heavy metal ions in ... |
