Removal of Octylphenolethoxylate from Waste Water using Carbonized and Non Carbonized Agro Waste of Typhalatifolia

Removal of higher concentration of nonionic surfactant Octylphenolethoxylate with 10 moles of ethylene oxide (OPE-10) trade name, Octylphenolethoxylate from industrial effluents, using the carbonized stem of aquatic weed Typhalatifolia, has been discussed in the present investigation. Carbonization of Typhalatifolia stem was done in the laboratory by using Muffle furnace instrument at temperature 500oC. The removal of surfactant is calculated by U-V spectrophotometer using cobalt thiocyanate active substances (CTAS) method. Various concentrations of surfactant solutions in the range from 200ppm to 1000ppm have been prepared for extraction work. Optimization of the experiments is done by calculating variables – shaking time, doses of absorbent bed and concentration of reagents. Degree of adsorption is validated and compared with isotherm models of Langmuir adsorption isotherms, Freundlich adsorption isotherms, Temkin adsorption isotherms Dubinin-Radushkevich adsorption isotherms and Harkin Jura isotherms. R 2 value among all isotherms best suited is Freundlich adsorption isotherm. SEM images of non-carbonized and carbonized agro-waste are also analyzed and compared. The variance of ANOVA was considered significant at p = 0.25.
