Preparation of basic yttrium carbonate for phosphate removal

Removal of phosphate ions from aqueous solutions has been studied with basic yttrium carbonate (BYC) of different compositions prepared by homogeneous precipitation with yttrium chloride and urea. Higher carbonate content was obtained with higher concentration of urea. Removal of phosphate was signi...
