摘 要:
采用HD-8微色谱柱对高稀土铁矿石样品(白云鄂博矿)中的钍进行分离富集,探讨了影响其分离富集的条件。实验表明,在4 mol/L HCl介质中钍可被树脂完全吸附,用3 mL 40 g/L草酸铵溶液可以从吸附柱上完全解吸钍,并结合偶氮胂Ⅲ分光光度法进行测定。所建立的方法适合于含铁、稀土量高的矿石样品中微量钍的分离与测定。[著者文摘]

Abstract:
The optimum conditions of separation and preconcentration for thorimn are studied in this paper. Thorimn is adsorbed by HD-8 resin in 4 mol/L HC1 solution, and eluted completely by using 3 mL of 4% ammonimn oxalate, then determined by spectrophotometry. The method is simple, accurate and applicable to the separation and determination of trace thorimn in lanthanoniron ore samples.[著者文摘]
