STUDY ON ADSORPTION OF DYE ORANGE II WITH MAGNETIC CETYLPYRIDINIUM BROMIDE
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
The magnetic cetylpyridinium bromide was prepared and characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) and other techniques. It can be used as adsorbent for removal of the dye orange Ⅱ pollutants in wastewater. The effect of some factors on the adsorption effect was studied, such as the concentration of orange Ⅱ, reaction temperature and pH value. The experimental results showed that the magnetic cetylpyridinium bromide has better adsorption capacity for orange Ⅱ. The adsorption amount increases with the increase of initial concentration and temperature. When the pH is 4, the adsorption amount reaches the maximum. Adsorption kinetics indicated that the adsorption process of orange Ⅱ by magnetic cetylpyridinium bromide was more consistent with the pseudo second-order reaction model. The isothermal adsorption linear fit shows that the adsorption of orange Ⅱ on the magnetic material conforms to Langmuir isothermal adsorption. The maximum adsorption capacity is about 270.27 mg/g.
