HNO_3修饰的亚麻废料吸附剂对锌离子吸附性的研究

Adsorption of Zinc Ions by Modified HNO_3 Flax Waste Adsorbent

利用亚麻废料制备吸附剂对废水中金属锌离子的吸附进行研究.结果表明,经HNO3修饰的亚麻废料吸附剂对锌离子吸附效果要好于未经修饰的亚麻废料.经HNO3修饰的亚麻废料吸附剂对锌离子有最佳吸附的pH为5.80,振荡时间120min达到吸附平衡,最大吸附量为0.324mol/kg,最佳固液比为4.3mg/mL.

Preparation of adsorbent used linen scrap metal in wastewater to study the adsorption of zinc ions. The results show that,after HNO3 modified flax waste adsorbent for zinc ion adsorption is better than the unmodified flax waste.HNO3 modified flax waste by the adsorbent the best absorption of zinc ions,pH 5.80,the oscillation time of 120min to reach adsorption equilibrium,the maximum adsorption capacity of 0.324mol/kg, best solid to liquid ratio 4.3mg/mL.
