茶叶中10种重金属浸出率
Leaching Rates of Ten Heavy Metals in Tea
摘要
Abstract
With ICP‐AES method ,heavy metals in tea infusion ,including Cd , Cr , Cu , Fe , Ni , Pb , Ti , Co , Mn and Zn ,were detected under different tea soaking conditions .The results showed that suitable conditions of soaking tea could effectively control heavy metal intake within minimum range .Leaching rates of heavy metals were compared between different tea kinds with same soaking conditions or among three soaking conditions for same tea . Results showed that the leaching rates of heavy metals in tea were related to the source of heavy metals .Heavy metals in tea originated from the soil were difficult to leach ,whereas heavy metals originated from atmospheric precipitation or introduced during the machining process were easier to leach .关键词
