The present investigation is focused on the use of TETA grafted nanobiocomposite (Aloe gummushroom nanopowder) for the removal of EDTA-metal complexes (EDTA-Zn, EDTA-Ni and EDTA-Ag) from aqueous environment. Batch studies were conducted in single, binary and ternary system. At an acidic pH of 3.0 and a molar ratio of 0.06:0.06, the COD removal and metal uptake followed the following order : EDTAZn (99.1{\%}) {\textgreater} EDTA-Ni (98.4{\%}) {\textgreater} EDTA-Ag (97.5{\%}). The overall COD removal potential was reduced to 92.1{\%} in ternary system. Equilibrium and kinetic studies suggested a homogeneous mode of intra-particle diffusion as the major mechanism. Further elucidation was done using FT-IR, SEM/EDX and XPS analysis. PVA-alginate immobilized nanobiocomposite was packed in a column for the remediation of electroplating and municipal wastewater. Among the three bead system in column, 1000 bead system exhibited maximum COD removal and found to be more suitable for the remediation of electroplating wastewater.
