摘　　要：为了解木鱼石袋泡茶含有哪些金属元素 ,以及浸泡时间和温度对其所含金属元素浸出量的影响 ,利用ICP AES和AAS法对其消化液和浸泡液 (滤纸过滤 )中的金属元素进行测定。结果 :木鱼石含有铁、铜、锌、锶等人体必需微量元素 ,其中铁的含量最高 ,对人体有害的铅、铬等元素未检出 ;浸出最佳条件为水温 10 0℃ ,时间 1h。结果提示 ,饮用木鱼石袋泡茶 。In order to understand what mental elements Muyushi Bag Tea contains and to investigate influence of the soaking time and temperature on extraction of its contained metal elements,metal elements in its digestive juice and soak(filtrated with paper)were determined by ICP AES and AAS.The results showed the trace elements of iron,copper,zinc and strontium,indispensable for the human body,were contained in Muyushi,with highest content in iron.The elements harmful to the human body,such as lead and chromium,were not discovered.The best condition was water temperature in 100℃ for one hour.The findings indicate that to drink Muyushi Bag Tea is beneficial for supplementing some trace elements not enough taken from normal diet.
