摘要
废弃枇杷核经粉碎和沸水预处理后得到一种枇杷核渣吸附剂,将其应用于甲基橙吸附试验。吸附结果表明,该枇杷核渣吸附剂对甲基橙有较好的吸附,在pH值为8~10时吸附能力最好,80 min时达到最佳吸附效果。当吸附剂投加量为0.25 g时,既保证了吸附剂用量较少,又保证了有相对较高的甲基橙去除率。温度对吸附的影响不大。本实验结果为有效利用废弃枇杷核对甲基橙废水的处理提供了较好的理论依据。
A loquat kernel slag adsorbent was obtained by crushing waste loquat kernel and then treating with boiling water. Its adsorption property for methyl orange was investigated. The adsorption results showed that the loquat kernel slag had good adsorption ability for methyl orange. The best adsorption effect was obtained at pH 8 - 10 and 80 min for absorption. The 0. 25 g of adsorbent dosage ensured a relatively high removal rate of methyl orange with less dosage of adsorbent. Temperature had little effect on adsorption. This result provided a good theoretical basis for the effective use of waste loquat for adsorption of methyl orange in wastewater.
