In this study, the usability potential of composite as a novel, cost-effective, and dual-function adsorbent, prepared by easy ball milling method, using carbonized forms of industrial wastes such as hawthorn waste pulp and marble waste powder was investigated to remove Remazol Brillant Blue R and mercury from aqueous environments. Response surface methodology was applied to define the effect of variables on adsorption and to optimize process conditions. In optimum conditions, removal efficiencies were obtained over 95% for both adsorption processes. Langmuir model was the most appropriate for both adsorption equilibria indicated that the adsorption processes occurred in single-layer homogeneous surfaces. Thermodynamic evaluations indicated that both adsorption processes were endothermic and spontaneous and had an increasing entropy. Moreover, the rate-limiting step of processes was identified with pseudo-second-order kinetic model. The composite showed a well-developed porosity and high surface area in addition to functional structures and active surfaces capable of adsorbing.

在这项研究中，研究了通过容易的球磨法，使用碳化形式的工业废料（如山楂废浆和大理石废粉）来去除Remazol的复合材料作为新型，经济高效且具有双重功能的吸附剂的潜在用途。水性环境中的亮蓝R和汞。应用响应表面方法来定义变量对吸附的影响并优化工艺条件。在最佳条件下，两种吸附过程的去除效率均超过95％。Langmuir模型最适合两种吸附平衡，表明吸附过程发生在单层均匀表面上。热力学评估表明，两种吸附过程都是吸热的和自发的，并且熵增加。而且，用伪二级动力学模型确定了过程的限速步骤。除了功能结构和能够吸附的活性表面之外，该复合材料还具有良好的孔隙率和较高的表面积。
