Table 5

Effect of carrier concentration on transport of rare earths.

rare earth metal	(min); Migration time (min)	item	Data results
La(III)	125	(mol/L) carrier concentration (mol/L)	0.036	0.065	0.100	0.160	0.230
		−ln/c0	1.34	1.98	2.33	2.80	2.83
		(m/s)	1.1910^−5	1.7610^−5	2.1610^−5	2.4910^−5	2.5210^−5

Note. Ct and C0 express concentration at time of t and the initial concentration of rare earth metal, respectively, unit: mol/L; Pc expresses permeability coefficient, the unit: m/s.
