Recently, attention has been drawn to the use of bio-reinforced composites in many fields due to increased concern for
environmental sustainability. This study was conducted to assess the adsorption efficiency of polymer-based composite
beads for removal of Cu and Ni fromwaste water. For this purpose, cellulose, sodium alginate and Hydroxy Apatite (HA) beads
were synthesized. The materials used have environmental importance and are widely covered in green chemistry. A factorial
design approach was conducted to establish the optimum conditions for the adsorption of heavy metals ions. The developed
beads were characterized using Fourier Transform Infrared spectroscopy (FTIR), X-Ray powder Diffraction (XRD), Scanning
Electron Microscopy (SEM) and Thermogravimetric Analysis (TGA). Presence of characteristic functional groups, surface
morphology, thermal stability and percentage increase of cellulose was evidenced by these characterization tests. The effect of
various experimental parameters on adsorption such as contact time, pH, initial metal concentration and adsorbent dose was
studied during removal process. The adsorption process was fast with adsorption equilibrium achieved at 20 minutes for Cu
and 30 minutes for Ni. It was found that the experimental data is best fitted with Langmuir isothermmodel. The kinetic studies
revealed that it follows pseudo second order kinetics. Increase in percentage cellulose caused increase in adsorption capacity.
Maximum adsorption capacity for Cu and Ni was found to be 39.71 mg/g and 41.95 mg/g on beads with 60% cellulose.
