Rare earth elements in tropical surface water, soil and sediments of the Terengganu River Basin, Malaysia Noor Azhar Shazili1,Khawar Sultan1 (1.Institute of Oceanography,University Malaysia Terengganu,Mengabang Telipot,21030 Kuala Terengganu,Terengganu,Malaysia) Abstract:The 14 stable rare earth element (REE) concentrations and distribution patterns were investigated for surface waters (n=51......
(0.869×10-10m), and it usually coexists with lanthanide series in the nature. Therefore, Y, together with scandium, is also called rare earth element. In general, the partition of yttrium is above 10%, even up to 50% in some weathered crust ores such as Longnan ore. Y is regarded a heavy rare earth element because its properties and radium are similar to those of heavy ones, which is also supported......
