Abstract

This article aims to determine the most effective ZnO-zeolite synthesis method for use as an adsorbent. The effectiveness of the ZnO-zeolite synthesis method includes the methods of synthesis, characterization, and adsorption. This study is a literature search using Google Scholar and Science Direct with the keywords “ZnO”, “zeolite”, “synthesis”, and “adsorption” taken from the last 10 years (2013-2023). Twenty-six articles were obtained, and selection was carried out so that 12 articles were obtained. There were 4 methods for ZnO-zeolite synthesis: (1) sol-gel, (2) impregnation, (3) coprecipitation, and (4) hydrothermal methods. The synthesis of ZnO-zeolite products was characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM), and their adsorption capacity was tested via UV-Vis spectroscopy. The hydrothermal synthesis method is the most effective method for the synthesis of ZnO-zeolite because it does not consume a large amount of energy, is a simple synthesis procedure, and has a large adsorption power. The resulting ZnO-zeolite has a crystal size of 1.540 mm and can adsorb up to 657.895 mg/g of the adsorbate).

Abstract

Peat soil contains functional groups such as carboxylic acid and hydroxyls that bind metal ions and organic compounds in solution. However, the adsorption capacity of natural peat soil is still considered low. Therefore, this study aims to alter the peat surface using a hydrogen peroxide solution and to utilize the resulting peat as an adsorbent for K+ ions in an aqueous solution. Peat soil was treated with a 10% hydrogen peroxide solution for 30 minutes. The infrared spectra of the treated peat indicated an increase in the intensity of hydroxyl groups (-OH) at 3400 cm-1 and a sharp increase in carboxylic groups (-COOH) at 1700 cm-1. SEM photos showed that the porosity of the treated peat was higher, probably due to oxidation reactions that resulted in new pores on the surface, and BET analysis confirmed the increase in surface area upon treatment. During the adsorption experiment, the residual concentrations of K+ ions were determined using AAS. The adsorption capacities of raw and treated peat were 37.40 mg g-1 and 59.53 mg g-1, respectively. When fitted using Langmuir and Freundlich adsorption isotherm models, the adsorption data plots followed the Freundlich isotherm model, indicating reversible adsorption on heterogeneous surfaces. The Density Functional Theory (DFT) calculation showed that the interaction energy between peat soil and K+ ions was lower after treatment, indicating that K+ ions bind to exchange sites on the treated peat soil.

Abstract

The contamination of antibiotics in water bodies has increased significantly in recent years. Various treatments, including adsorption, have been sought, but most include expensive sorbent material with low efficiency. This research reported an alternative sorbent material; synthetic zeolite derived from coal-burning waste. Coal bottom ash was converted to zeolite via a hydrothermal technique using various concentrations of NaOH and relatively low-temperature conditions. X-ray diffractogram confirms the formation of ZSM-23 when a 1:2 coal-to-zeolite ratio was used at 95°C. The FTIR spectra also highlighted the characteristics of zeolite functional groups, such as the Si−O vibration at 999.56 cm-1 and the Al−O vibration at 799.48 cm-1. The needle-like morphology of ZSM-23 was observed during SEM-EDS analysis. When calculated using BET analysis, the synthetic zeolite also exhibited a high surface area of 433.517 m2 g-1. Upon application in a batch experiment, the maximum adsorption capacity of the zeolite for amoxicillin (AMX) adsorption in aqueous solution was found to be 673.5 mg g-1. The adsorption data fitted the Langmuir isotherm better than the Freundlich one, with a correlation factor of 0.9328. This suggested the monolayer interaction, possibly between the negatively charged zeolite surface and the NH3+ group from AMX. However, the physical adsorption mechanism with the zeolite surface may also occur due to the high surface area. Considering the low production cost, this zeolite offers high economic value as an alternative sorbent for removing antibiotics in water effluent.
