稀土泛指17種特性相似的金屬，較常用在作醫療設備之上，其中一種 (Promethium, Pm)為具放射性的物質。126Please respect copyright.ＰＥＮＡＮＡNiwr9VoGtr

雖然它們被稱為稀土，但事實上它們並不真的是如此稀有。126Please respect copyright.ＰＥＮＡＮＡKKtV8a5SQZ
圖1圖中的圓點為各種稀土金屬蘊藏量，大部份與錫的含量相約，且遠高於大自然間的水銀含量。126Please respect copyright.ＰＥＮＡＮＡR0pBNdrSAD

（圖2）近日有科學家發表文章（Ref2)，從需要攝取稀土金屬才能運作的細菌中抽取一種名為Lanmodulin的蛋白質。126Please respect copyright.ＰＥＮＡＮＡqD2NsFCuTT

這蛋白質有三大特性，126Please respect copyright.ＰＥＮＡＮＡ9bwGRMtTKn
1.能夠選擇性地黏上稀土金屬，不會黏上銅鋅鎂等非稀土金屬。126Please respect copyright.ＰＥＮＡＮＡ8aWTMWiico
126Please respect copyright.ＰＥＮＡＮＡpDOPtXSQ8G
2.攝氏95度下仍然正常運作。126Please respect copyright.ＰＥＮＡＮＡWxmEZpmunD
126Please respect copyright.ＰＥＮＡＮＡ1ctVlG37gi
3.pH2.5酸性環境仍能正常運作。126Please respect copyright.ＰＥＮＡＮＡrUIrQJV8q0

對比常用的一種金屬提取物質EDTA，Lanmodulin不但之對稀土金屬更具選擇性，而且親和力更高出5-10倍或以上。126Please respect copyright.ＰＥＮＡＮＡTc5kNTRODG
126Please respect copyright.ＰＥＮＡＮＡb54mOhrfhO
（圖3）電子廢物普遍會溶解在pH3.0的酸性環境使金屬呈離子狀態，有著Lanmodulin的幫助下，舊有的繁複及高能源消耗的提取稀土金屬辦法亦將能逐漸退出市場，各國亦能更有效從各電子儀器中回收稀土金屬，再進一步減少對中國的依賴。126Please respect copyright.ＰＥＮＡＮＡ6kSGM9km5u
