The study of Andisol/Zeolite/Fly ash (AZF) as adsorbents has been investigated. This research was aimed to study the characteristics of AZF as an adsorbent for Chromium metal ion removal. Andisol soil and zeolite were activated using NaOH solutions. All materials were characterized by Fourier Transform Infrared (FTIR), Surface Area Analyzer (SAA), and Ultraviolet-Visible Spectrometry (UV-Vis). Based on the results, the optimum composition of AZF was obtained at the ratio of andisol/zeolite/fly ash of 2.4/2.4/0.2 (w/w%), with a decrease on Chromium(VI) concentration above 92%. The optimum condition occurred at a pH of 3 and 150 minutes of contact time. The isotherm study showed that Freundlich isotherm was more dominant rather than Langmuir isotherm.

“…Clay minerals or claystone can be used as a catalyst, adsorbent, and as a resin for ion exchange, to exchange ions, clay must first be activated in order to increase the absorption of clay (Catherina, 2014). Claystone or claystone has great potential as an adsorbent because of its abundant, large surface area with active groups such as silanol and aluminol in its skeletal structure and easily dispersed in water (Pranoto, et al, 2018).…”

Research on the use of zeolite/clay/ activated charcoal composites as Hg heavy metal adsorbents has been carried out. Zeolites and clays were previously activated using NaOH, while activated charcoal was activated using HCl. The adsorbent characterization was carried out by Fourier Transform Infrared Analyzer (FTIR), X-Ray Diffraction (XRD), and mercury levels using Atomic Absorption Spectroscopy (AAS). Hg metal adsorption experiments were carried out by varying the composition of zeolite/claystone/ activated charcoal. The location of the study was Unlicensed Gold Mining (PETI) in the Kapuas watershed, Ulak Jaya Village, Sintang. The results showed that zeolite/claystone/ activated charcoal succeeded in reducing mercury levels in wastewater. The purpose of this study was to prove that the wastewater from gold mining could be reused to meet the needs of the community and improve environmental sustainability.

“…In addition, the reason for lower adsorption may be found in the formation of a film around the adsorbent, which prevents the adsorbate from accessing the surface. At the same time, the adsorbent capacity may be higher, because the higher initial concentration provides the necessary driving force to overcome liquid resistance [8,16].…”

A review of the studies dealing with the removal of chromium, cadmium, and nickel ions with different adsorbents published in the literature between 2014 and 2018 is given in tabular form, along with the adsorption conditions, adsorption isotherm, and kinetic models applied by the authors to model the experimental data and adsorption capacities. The review focuses on the efficiency of ion removal.
