The effectiveness of five plant oils (cottonseed, olive, canola sunflower and used cookingoil) for the removal of dye from textile wastewater was evaluated. The study revealed that the dyeremoval efficiency increased as the temperature was increased. Under low pH, both the oil and dyesplit into two components each. Neither one of the oil components joined with either one of the dyecomponents. However, the observed reduction in the absorbance under acidic conditions can beattributed to the dye components losing some of their original color or producing different colors thatwere not effectively measured at 475 nm. When the dye solution was shaken with the oil underalkaline conditions, it formed a colloidal solution containing the oil plus the dye, resulting in asignificant dye removal from solution. The results also showed that the optimum conditions for the dyeremoval for various oils were at a pH of 13 and a temperature of 55 °C, except for canola oil thatproduced the highest dye removal efficiency at pH of 7. The used cooking oil achieved the highest dyeremoval efficiency (95.45%) followed by olive oil (87.00%). The other oils (cottonseed, canola andsunflower achieved dye removal efficiencies below 58% and are, therefore, not recommended for dyeremoval. |
