| Abstract: | We should take action to deal with the bentonite to improve its magnetization,according to the limitation on the practical application.Bentonite-supported magnetite particles were prepared by co-precipitation and characterized by X-ray diffraction(XRD) and magnetization measurements.The adsorption effect of bentonite-supported magnetic particles on wastewater containing OrangeⅡwas tested.The effects of the dose of surfactant,pH and temperature on the removal were studied.Results showed that cation surfactant is useful for adsorption of OrangeⅡ.The process was less affected by pH in a wide range,when pH>7.4,the removal rates was reduced from 98.4% to 92.6%,and the removal was decreased with the increase of temperature.Compared with the organobentonite,not only the dispersion improved,but also the turbidities of the supernatants decreased.In the sedimentation time of 8 min,the turbidities of the supernatants are below 10 NUT. |
