The present investigation explores the efficiency of low-cost agrowaste adsorbent for removal of octylphenolethoxylate surfactant from industrial wastewater. The stem of two aquatic weeds Nelumbo nucifera and Typha latifolia have been used as an adsorbent bed. They were named as non-carbonized nelumbo nucifera (A), carbonized nelumbo nucifera (B), non-carbonized Typha latifolia (C) and carbonized typha latifolia (D). Biosorption capacity of these adsorbent beds was analyzed by pH meter and UV-visible spectrophotometer. The efficiency of adsorption capacity of surfactant was validated by three adsorption isothermic models (Freundlich, Halsey and Jovanovic). The result show that regression coefficient (R2) values of Jovanovic adsorption isotherm from pH meter were 0.942, 0.986, 0.930, 0.972 and from UV-visible spectrophotometer were 0.979, 0.983, 0.969, 0.971 for the agrowaste A, B, C and D, respectively. These values are higher than the rest of the two isotherms. Adsorbent B showed higher values among all beds by both techniques. It indicates carbonized nelumbo nucifera has more potential to interact with molecules of surfactant than the rest. Particle size of agrowaste was analyzed by SEM images, it showed bed B was more porous than other beds. FTIR spectra indicate the presence of functional groups of alkaloids and flavonoids in the absorbent beds, which gives sites for adsorbtion of surfactants. Statistical analysis was done by single factor ANOVA considering significant value p=0.01. Thus, the removal of octylphenolethoxylate from the industrial wastewater maybe possible by the agrowaste, which is eco-friendly, chemical free and biodegradable in nature.
