Adsorption Kinetics And Mechanism Of Pb(Ii), Cd(Ii) And Ni(Ii) Ion Sorption From Aqueous Medium Using Activated Calopo (Calopogonus Mucunoides) Seed Pod:- Aleruchi Christian C.
ABSTRACT
In
this research calopo seed pod an agricultural product, available in large
quantity in south region of Nigeria, were used as low-cost adsorbent for
removal of metal ions such as Pb(Il), Cd(ll) and Ni(ll). Batch operation was
used to study the equilibrium behavior of calopo seed pod. The effects of
solution pH, and contact time of adsorbent for Pb(II), Cd(II) and Ni(II) ions
were evaluated. To study the kinetics of adsorption of Pb(ll), Cd(ll) and
Ni(ll) onto calopo seed pod, pseudo-first-order, pseudo-second-order and
intra-particle diffusion( Weber and Morris, Mickey and Poot) model, Mass
transfer Model, and liquid film Models were used. Adsorption process undergoes
pseudo-second-order kinetic as proved by the high value of R2 (Pb(II) 52.63mg/g
>, Cd(II) 50.00mg/g > Ni(II) 47.67mg/g) and mechanism of adsorption show
that the process was intraparticle controlled - Weber and Morris Model with R2
values of Cd(II) 0.891mg/g > Pb(II) 0.761mg/g > Ni(II) 0.750mg/g. In
addition, the results indicates that calopo seed pods are very effective
adsorbent for the removal of for Pb(ll). Cd(Jl) and Ni(II) ions from aqueous
medium. This will serve as a parameter to consider in the design for waste
water treatment plant for heavy metal detoxification using calopo seed pod.
