| dc.description.abstract | Adsorption of dye-extract from Peristophe roxburghiana onto cotton fabric: Kinetic, thermodynamics and Isothermic evaluation was studied at different temperatures (50°C, 60°C, and 70°C) and concentration (2, 2.5, 3, 3.5, 4, 4.5, 5g/l). Peristophe roxburghiana (PR) plant leaf sample was extracted using aqueous extraction method for 40mins at 70°C. The plant extract was characterized using UV-VIS spectrophotometer and FTIR. The wavelength of maximum adsorption was at 580nm and the functional group identified at 1200.2 cm-1 , 1.323.3 cm- , and 3272.6 cm-1 in the plant extract showed that the dye is an Anthocyanin dye as it contains hydroxyl (OH+ ), ketone (CO- ), hydroxylated aromatic ring. The adsorption mechanism was affected by temperature and concentration while its kinetic pattern obeyed pseudo second order model and type 1 Langmuir isotherm model perfectly. Thermodynamic parameters values 3438.4J/Mol for (ΔH°) and -9.991 J/Mol/K(ΔS°) respectively revealed the reaction was endothermic in nature. This study also showed that the reaction of the dye is chemisorption with a definable adsorption mechanism. In conclusion, a design for colour control and colour optimization can be achieved with proper understands of the adsorption behavior of the dye extract from this plant leaf. | |
