Table 4. Barium absorption in the indicated percent of weight of MF-HT.

Percent of MF-HT (wt/wt)	Barium concentration Mean ± SD (µg/L) (n = 3)
0.001%	962.30±23.83
0.010%	621.40±19.77
0.100%	270.63±35.40
1.000%	71.80±8.52

After the indicated percentages of weight of MF-HT (percent of MF-HT) had been suspended in solutions containing 1,000 µg/L barium, the MF-HT-suspended solutions were shaken at 300 rpm for 1 hour. Barium concentrations (means ± SD) in the supernatants after the solutions had been centrifuged are presented.
