the rate determining step. The reaction shows both 1st
order dependency on [benzyl alcohol]T and [Cr(VI)]T
and 2nd order dependency on [H+] ion. In the presence of
some non-functional surfactants, the orders remain un-
changed. CPC has been found to retard the rate while
SDS and TX-100 shows the rate acceleration effect (Ta-
ble 2). The effect of added electrolye gives different ob-
servations. Inhibition followed by enhancement is the
effect of NaCl but for NH4Cl inhibition is the only fate.
So for waste water treatment with biosorbent, SDS or
TX-100 and suitable concentration of NaCl may be used
for quick result.
