摘要
用微波消解和浸泡法对茶叶进行处理,通过石墨炉原子吸收光谱法分别测定茶叶和茶水中铅的含量.结果表明,所测茶叶样品铅含量都没有超出国家限量标准,茶水中铅含量几乎为零,符合饮用安全标准.
The tea was treated by microwave digestion and soaking,then the content of lead in tea and tea water was determined by graphite furnace atomic absorption spectroscopy separately.The results show that the lead content of the tea samples determined isn’t beyond the national defined standard and the lead content in tea water is almost zero,which conforms to drinking safety standards.
