“…Alternatively, (SH)silica shows quantitative sorption only to As(III) at the two extreme points in the investigated pH range, namely, pH 1.0 and 9.0 while As(V) is not retained. This result is in accordance with similar literature studies which suggest that mercapto group is selective generally to the lower oxidation states of the hydride forming elements [30,31,35,36]. On the other hand, (NH 2 )silica demonstrates selectivity only towards As(V), and this response is indicative of the affinity of amine functionality to arsenate ion.…”

“…7. From these results it can be suggested that the decrease in percentage Time (min) 35 sorption can once again be referred to the change in the solution pH, and is not a consequence of the reaction time. This conclusion can also be drawn from Fig.…”

“…[13][14][15][16] Thiol cotton fiber (TCF) is also used for the preconcentration and chemical separation of antimony. 13,17 However, the results from the preconcentration and chemical separation for antimony using TCF varied among those studies.…”
