ABSTRACT

A novel maize tassel-ethyl acrylate biopolymer embedded

magneticnanohybrid(MTEA-MN)was designed for the adsorption of Cd (II) in batch

experiments.Copolymerization parameters such as solvent amount, initiator

concentration, monomer concentration, temperature and reaction time on grafting

percentage were optimized.Characterization of the adsorbent was byFourier transform

infrared spectroscopy (FTIR). The effect of pH, contact time, initial concentration and

adsorbent dosage and their interaction influence on Cd(II)

adsorptiononwasinvestigated using response surface methodology following a central

composite design (CCD). The optimum removal (95.26%) was obtained at pH 3.5,

contact time 240 min, adsorbent dosage 0.53 g and initial concentration 44.6

mg/Lusing the GRG non-linear solving method on Excel solver. The data best fitted

the non-linearLangmuir adsorption model with greaterR2(0.998)smallersum of square

deviation (SSD) value (1.6956) relative to Freundlich model with R2= 0.974 and SSD

= 2.8786. The maximum sorption capacity of the MTEA-MN for Cd (II) was 459.37

mg/g. Kinetics studies revealed that the adsorption process followed the pseudosecond

order model (lowest sum of square error (SSE) values and correlation

coefficients (R2) >0.9). The calculated thermodynamic parameters showed that the

adsorption process was feasible, spontaneous and endothermic in nature.

Consequently, the present study demonstrated that MTEA-MNcould be used as an

adsorbent for the removal of Cd (II) ions from aqueous solutions.
