| 摘 要： | Macroporous amino-carboxvlic chelating resin of acrylic acid series may concentrate trace rare earth inthe presence of 0.1 mol/l α-hydroxy-isobutyric acid at pH 4.5.With 0.10 mol/l HCl as eluant rare earthmay be eluted quantitatively and separated from Ca,Mg,Fe and Cu.This method is used to determine traceamount of rare earth in human hair,stone (in kidney and bladder),peanut,grape,strawberry,cucumber,pigliver and other biological samples. |
