Limestone and coffee waste were used during the wet co-granulation process for the production of efficient adsorbents to be used in the removal of anionic and cationic dyes. The adsorbents were characterized using different analytical techniques such as XRD, SEM, FTIR, organic elemental analysis, the nitrogen adsorption method, with wettability, strength and adsorption tests. The adsorption capacity of granules was determined by removal of methylene blue (MB) and orange II (OR) from single and mixed solutions. In the mixed solution, co-granules removed 100% of MB and 85% of OR. The equilibria were established after 6 and 480 h for MB and OR, respectively.
在湿式共造粒过程中使用石灰石和咖啡渣来生产高效吸附剂，用于去除阴离子和阳离子染料。采用不同的分析技术对吸附剂进行表征，如X射线衍射（XRD）、扫描电子显微镜（SEM）、傅里叶变换红外光谱（FTIR）、有机元素分析、氮吸附法，并进行润湿性、强度和吸附测试。通过从单一溶液和混合溶液中去除亚甲基蓝（MB）和橙黄II（OR）来测定颗粒的吸附容量。在混合溶液中，共颗粒去除了100%的MB和85%的OR。MB和OR分别在6小时和480小时后达到平衡。
