Yttrium hydroxide quantitatively coprecipitated Be(II), Ti(IV), Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), and Pb(II) at pH 9.6 - 10.0 for seawater and pH 10.5 - 11.4 for a table-salt solution. The coprecipitated elements could be determined by inductively coupled plasma atomic emission spectrometry; yttrium was used as an internal standard element. The detection limits ranged from 0.001(6) microg (Mn(II)) to 0.22 microg (Zn(II)) in 100 mL of sample solutions. The operation time required to separate 11 elements was approximately 30 min.
氢氧化钇在海水pH值为9.6 - 10.0以及食盐溶液pH值为10.5 - 11.4的条件下，能定量共沉淀铍（II）、钛（IV）、铬（III）、锰（II）、铁（III）、钴（II）、镍（II）、铜（II）、锌（II）、镉（II）和铅（II）。共沉淀的元素可用电感耦合等离子体原子发射光谱法测定；钇用作内标元素。在100 mL样品溶液中，检测限范围为0.001(6)微克（锰（II））至0.22微克（锌（II））。分离11种元素所需的操作时间约为30分钟。
