摘要
The sludge-straw adsorbent was prepared by chemical pyrolysis and characterized by Brunauer Emmett Teller (BET), T-plot, Barrette Joynere Halenda (BJH), scanning electron microscope (SEM) and Fourier transform infrared red (FTIR) spectrometer. Batch experiments were conducted to evaluate the effect of temperature, contact time, initial dye concentration, pH and adsorbent dose. Adsorption mechanism of acid violet 48 onto the sludge-straw adsorbent had been discussed preliminarily on the basis of different kinetics and adsorption isotherm models. The results showed that the pseudo-second order adsorption mechanism was predominant. The maximum adsorption capacity obtained from Langmuir model was 833.33 mg/g at 308 K. Isotherm parameters were calculated, the results indicated that the adsorption processes were endothermic (Delta H > 0), spontaneous (Delta G < 0) and accompanied by an increase in randomness (Delta S > 0).
