The concentrations of ferrocyanide that was produced by the reduction of ferricyanide were directly estimated by chronoamperograms. Furthermore, the limiting current can be converted to equivalent inhibitory percentage values following Eq. (1): %inhibition =[1 −(ilim(toxicant) − ilim(t−control))/(ilim(p−control) − ilim(n−control))]¡Á 100 (1) where: ilim (toxicant): output of limiting current at a appropriate con- centration of toxicant and standard GGA198 solution; ilim (t-control): output of limiting current at a appropriate concentration of toxi- cant andnoGGA198 solution;[quote][quote] ilim (p-control): output ofpositive control current; ilim (n-control): output of negative control current. |
