Determination of Terbium(III) Ions in Phosphate Rock and Different Water Samples abstract
Terbium is classified as a rare earth element. Terbium is never found in nature as the free element, but it is contained in many minerals, including cerite, gadolinite, monazite (Ce, La, Th, Nd, Y) PO4, which contains up to 0.03% of terbium), xenotime (YPO4) and euxenite (Y, Ca, Ce, U, Th)(Nb, Ta, Ti)2O6, which contains 1% or more of terbium. As with the other lanthanides, terbium compounds are of low to moderate toxicity. In this work, A poly (vinyl chloride)-based membrane of N, N-Dimethyl-N', N"-bis(4-methoxyphenyl)phosphoramidate (DMP) as a neutral carrier was prepared and investigated as a Tb3+-selective sensor. The membrane sensor was applied to the Tb3+ recovery from different water samples, determination of fluoride ions in mouth wash samples and the determination of Tb3+ in phosphate rock samples.
