【 摘 要 】

The adsorption treatment of malachite green (MG) wastewater using fallen acer monoes leaves as adsorbent has been studied. The effects of single factors such as adsorption oscillating time, pH value, fallen acer monoes leaves dosage, temperature, initial MG concentration and salts concentration on MG adsorption on fallen acer monoes leaves have been investigated, respectively. The results show that the major effect factors on adsorption are including adsorption time, adsorbent dosage, pH value and salts concentration. Through the analysis of the orthogonal test, it is confirmed that the effect orders of the MG adsorption rate from master to the secondary were NaCl concentraction, pH value, fallen acer monoes leaves dosage, oscillating time. The adsorption efficiency of MG on fallen acer monoes leaves could obtain 95.2% at he optimum condition of acer monoes leaves dosage of 3g/L, oscillating time of 5min, pH value of 7.0, NaCl dosage of 0.08mol/L. Fallen acer monoes leaves have a good effect on the adsorption of MG wastewater.
