This paper presents the data for the effect of adsorbent dose, initial sorbate concentration, contact time, and pH on the adsorption of chromium(VI) on maple sawdust. Batch adsorption studies have been carried out. An empirical relationship has been obtained to predict the percentage chromium(VI) removal at any time for known values of sorbent and initial sorbate concentration. Under observed test conditions, the equilibrium adsorption data fits the linear Langmuir and Freundlich isotherms. The experimental result inferred that chelation ion exchange is one of the major adsorption mechanisms for binding metal ions to the maple sawdust.
本文介绍了吸附剂用量、初始吸附质浓度、接触时间和pH值对枫木锯末吸附六价铬效果的数据。进行了批量吸附研究。已获得一种经验关系，以预测在已知吸附剂和初始吸附质浓度值的情况下，任何时间六价铬的去除百分比。在观察到的测试条件下，平衡吸附数据符合线性朗缪尔等温线和弗伦德里希等温线。实验结果推断，螯合离子交换是金属离子与枫木锯末结合的主要吸附机制之一。
