Study on the Removal of Paper Absorbent to Alkaline Printing and Dyeing Wastewater

Abstract:

A new type of adsorbent which prepared with waste paper as raw material was applied in the treatment of dye wastewater, and studied the processing conditions on treatment effect. Batch adsorption study carried out as a function of the dosage, the stirring time, the stirring speed and the pH. The adsorption rate of newspaper adsorbent to basic blue dye simulated wastewater and alkaline yellow wastewater with an initial concentration of 80mg·L^-1 can reach 98.56% and 92.23% at 4g·L^-1 of the dosage of paper adsorbent, 15min of the stirring time and 150r·min^-1of the stirring speed. The maximum adsorption were 233.1g·L^-1 and 289.4g·L^-1 respectively. The isothermal adsorption experiment was also studied and concluded that the adsorption equilibrium data fitted with the Langmuir isotherm. The characterization experiment showed that the modified paper adsorbent had stronger absorbability.
