Abstract:
Sheep manure wastes (SMW) previously have been shown to be very
efficient in removing nickel and cadmium from single-component, dilute
aqueous solutions. Simultaneous removal of nickel and cadmium ions
from aqueous solutions usingSMWhas been investigated in this study. The
experimental results showed that the SMW has a relatively higher affinity
for cadmium binding than that for nickel. Different multicomponentisotherm
models; extended Langmuir, modified Langmuir, extended
Redlich?Peterson, and extended Sips isotherm models, were used to
predict the removal of either ions using single metal isotherm data.
